1. they need less than 5 g of food per day. Ammonia gas (NH3) is formed from dissolved ammonium (NH4+) at higher pH (the higher the pH, the greater the amount of ammonium is converted to toxic ammonia). I called Seachem and got the scoop. According to the safety data sheet of the Seachem Matrix filter media, this filter medium is nothing but 100% pumice. Then 46 ppm of NH3 was added to both aquariums again. production of toxic compounds). Thank you for getting in touch with our support team about this. Seachem Matrix vs. pemza. Another experiment that was not done by me, but by one American aquarist who gave me permission to describe it here. in the conversion of complex organic compounds into simple inorganic plant nutrients) remains to be verified. was able to remove up to 46 ppm of NH3 with the added filter media. But for this purpose, I think it is preferable to use activated carbon in combination with some fine mechanical filtration. With Matrix, you know it isn’t going to affect your pH or leach anything into your tank. Initial water parameters: KH 7, GH 12, pH 7.6, Water temperature: 77-84°F (25-29°C) [active cooling with small fans], Brand of the drop test kit used: API suggesting that the filter media provide at least a comparable colonizing area as the removed biofilm. BigXor. With Matrix, you are assured to not leach anything in your tank water. Un material mucho más efectivo en filtración biologica de acuarios. A high concentration of ammoniacal nitrogen results in an increase in nitrite concentration, which is converted by bacteria into nitrates. The Planted Tank Forum > Specific Aspects of a Planted Tank > Equipment > Best Biological Media 4 Filter - Seachem Matrix vs Fluval BioMax Reply. Prior to the next test, the filter and aquarium went through a thorough cleanup consisting in removing all the biofilm that formed on the filter- as well as aquarium walls (cf. The importance of filtration (or filter media) appears to be overestimated (at least in terms of nitrification). . and subsequent proliferation of algae, are (given the enormous nitrification capacity of the empty aquarium) most likely nonsense. This test should verify if most of the nitrifying bacteria were concentrated in the filter medium or is located elsewhere (e.g. Yes most porous media will promte some growth of anaerobic over time. It’s a very porous media that provides excellent biological filtration in all types of aquariums. For comparison, I refer to a common pumice of various grain sizes: generalpumiceproducts.com. Certified Seachem technical support specialists are active Monday-Friday, 9:00 AM-5:00 PM EST. The effect of bacteria mixtures in aquarium cycling, [Leftmost aluminium basin (volume approx. … After thorough cleaning of the filter and treating the water with a double dose of Seachem Prime, 1ℓ of a cycled Fluval Biomax filter media It is said in the fish farming literature that about 30-34 m2 of filter media area is needed to break down the ammoniacal nitrogen produced from 1 kg of fish feed at the water temperature of 77°F (25°C). It's hard to blame marine pure directly because this could have been from PVC or something else. In addition, some filter media will soon become clogged with organic detritus or inorganic precipitates, and anaerobic decomposition will begin to occur with all the negative consequences (e.g. it is important to often change large amounts of water. It is also quite possible that many filters may increase ammonium concentration in the aquarium rather than reduce it effectively. A complete filter media (= 1ℓ) was removed from the Fluval Biomax aquarium and moved to the Bare Tank. /';this should keep you in media for years. during the whole experiment (see the next picture). Aerobic microbes are needed to convert ammoniacal nitrogen to nitrites and subsequently to nitrates. (which would clearly indicate that the filter media have virtually no effect on the nitrification efficiency), 6.5G = 25ℓ).]. Some filters may function as "traps" and producers rather than "degraders" of organic waste. There was an experiment done on The Planted Tank forums using this stuff vs Seachem Matrix, and this stuff actually seemed to cycle the tank faster than Matrix … Seachem Matrix Biological Media. I have found not only is the pond matrix far cheaper in bulk but the larger size pieces seem to actually make it work better too. Well, isn't it interesting - lol. (up to 76 ppm of NO. Subsequently, 16 ppm of NH3 was added to the water. Dumping loose pumice rocks into the basket will be a royal PITA when it's time to clean the filter. Author of the test: Linn Fahrenkrug (Immortal1) from Iowa, USA. The rest (99.998%) belongs to heterotrophic bacteria. If all the filter media was removed from the Aquatop filter, and yet it was able to break down most of the ammonia, Its much simpler, safer, and cheaper than bringing in that beautiful live rock at a very high price and a lot of nasty critters. As can be seen from the pictures above, the bacteria in the filter media were able to remove 16 ppm at first, and the next day 33 ppm NH3 per 24h, Next criteria is the size of pores in the medium. it would mean that the filler itself does not play very important role in the nitrification. ... stones added to increase the weight ..same powder stuff like a chalk and also picture of one stone to show the real pumice stone I.e matrix vs stones ..you can tell by the weight the difference Read more. Few, however, know that nitrification is only the tip of the iceberg in different kinds of decomposition processes. Seachem Matrix. It took me 6 months to figure this out. This means that only 0.17 m2 of the filter media area (34*0.005) is sufficient to break down the ammoniacal nitrogen produced by the fish from 5 grams of feed. The use of filter media in the filter is most likely unnecessary (at least in terms of nitrification) in a planted aquarium with a reasonable fish stock. When I switched to matrix I didn't have the problem anymore. on filter walls, in hoses, and the like). It has a rough surface, which is perfect for bacteria. 200%) si deci si porozitatea ar trebui sa difere mult. asked on February 13, 2013. Of the total of 18 million bacteria in 1 gram of the top layer of filter sand, only about 425 bacteria (0.002%) belong to autotrophic nitrifiers. Bare Tank (empty aquarium) = 45ℓ aquarium with filter without any filter media. Matrix is pumice rock You can . But there is one very simple, yet important step you must take in order to unlock their full potential. it would mean that the filter media account for at least 50% of the total nitrification. The Seachem Matrix is a bio media made of solid pumice that has been processed into 10mm pebbles. Hello Jmacke! Seachem Matrix is nothing more than expensive pumice stone. Increased concentrations of dissolved organic matter in the water can then promote the growth of some algae. Sorry, the board is unavailable at the moment for maintenance. WATER CONDITIONER/TREATMENT ... stones added to increase the weight ..same powder stuff like a chalk and also picture of one stone to show the real pumice stone I.e matrix vs stones ..you can tell by the weight the difference. In the aquarium hobby, the idea (or rather the myth) spread that for the removal of ammoniacal nitrogen (NH3/NH4+) from the aquarium water Pro srovnání uvádím odkaz na obyčejnou pemzu o různé zrnitosti: generalpumiceproducts.com. It is … If filter media did not cope with the given amount of ammonia, it would suggest that filter media are most likely not the place where nitrifying bacteria concentrate. Thank you for visiting the Seachem Support and Discussions Board. 1ℓ Seachem Matrix = 500,- Kč Seachem are great marketers, but not always that great when it comes to providing actual scientific data to back up their claims. it is necessary to use a good biological filter with a large colonizing area for a sufficiently large colony of nitrifying microbes. Bare Tank (empty aquarium) = 45ℓ aquarium with Eheim Pro II 2028 filter without filter media. Consequently, with high production of ammoniacal nitrogen, nitrates will accumulate to a large extent in the aquarium Matrix certainly isn't the only biomedia you can choose. On Saturday, the filter was thoroughly cleaned and only 3 days later it was again covered with a continuous layer of biofilm Years ago Matrix was obviously pumice, a type of volcanic rock which doesn’t absorb water and floats. The filters compete with plants because some nutrients can often precipitate in them (most often iron and phosphorus). Porozitate redusa inseamna mai putine bacterii ( ni si deni - … Matrix is a solid pumice biomedia processed to form 10-mm pebbles. Warning: The difference from buying pumice in a store versus Seachem is presumably that the store won't clean it and guarantee that it's free of heavy metals. For an idea: This amount of ammonia is produced by more than 10 kg of adult Neon Tetras in 24 hours. dead fish decaying somewhere unnoticed) may not pose any problem for an already established colony of nitrifying bacteria, (or 10 kg of well fed fish). What you want to do is clean them under softly running water that’s around room temperature. The goal of this test was to find out what share in the total nitrification the filter media themselves have. Amazon usually has 1-liter containers of Matrix for around $11. In cazul Matrix vs "Matrix", pietrele par sa fie din aceiasi origine (vulcanic pumice), acelasi material (compozitie) daca le spargi, dar greutatea/volum difera Foarte mult (aprox. This usually means to have a very porous filter media. Specifically designed for the Fluval U2/U3/U4 filters, BIOMAX provides an optimal environment for the colonization and growth of beneficial bacteria. From the above experiment many interesting things follows: For an idea of how much ammoniacal nitrogen is generated from 2 g of fish food, which is the recommended feed dose for 100pcs of adult (2 inches [5 cm] long) Neon Tetra in 25G (100ℓ) aquarium: 100 pieces of Neon Tetra fed daily by 2 g of feed produce less than 0.055 g = 55 mg NH3 every day, which when dissolved in 25G (100ℓ) aquarium is 0.55 ppm NH3. Read more. An empty aquarium (Bare Tank), which, without filter media, was able to completely remove 30.6 ppm of NH3 at most in 24 hours, In my point of view, the stuff from Seachem for that is the best one. This is the second item that’s worth checking out. Matrix is made out of refined pumice stone . resulting in total collapse of nitrifying bacteria (the bacteria either died out or no longer broke down NH4+ and NO2-, Sponge = 12G = 45ℓ aquarium with inner sponge filter (designed for 20G = 75ℓ aquarium). This experiment refutes the widespread myth that we need the most efficient filtration with as much filtration area as possible to remove toxic ammonia from the water. Regarding nitrification, it seems to be proven that filtration (or filter media) is superfluous in a normal, well-functioning planted aquarium. which intake the fish and plants can't control, and is therefore potentially much more toxic to them. Seachem Matrix. Thus, in order for nitrate levels in test aquariums not to increase to extremely high concentrations that can lead to the collapse (inhibition) of nitrification, The next day (after changing 100% of water and dosing the same amount of ammonia), the nitrite concentration started to rise again (see day #16). A: We certainly understand why people look at Matrix™ and compare it to pumice; they are both porous stones. Pumice stone is super porous and is supposed to be able to harbor denitrifying bacteria inside anaerobic areas deep inside the pumice stone . i.e. No Filter (aquarium w/o filter) = 12G = 45ℓ aquarium without filter, only with an air stone. Note: Pond matrix is the same as matrix just bigger pieces. To break down such an extreme concentration of ammoniacal nitrogen as 30 ppm NH, To say that there may be so-called "peaks" or mini-cycles in the aquarium, during which there is a local, short-term or sudden increase in the concentration of ammoniacal nitrogen, which can lead to the germination It has a much higher surface area than most live rock. So then I Googled "Matrix pumice" and found another forum conversation where the same thing was said. Matrix™ is a specific type chosen for its extremely high porosity, pore size, durability, and inert nature. seachem pond matrix 4l Box Contains. The amount of food that fish must consume daily to make them healthy and grow well is about 1.0-2.5% of their body weight. The day before the test, water was treated with. ], Bio Balls (plastic balls) = 12G = 45ℓ aquarium with filter, which has 275 mℓ (25pcs) of bio-balls as the medium. So I have 2 questions; (sorry for the thread hijack!) 1 ppm NH4+ = 2.55 ppm NO2- = 3.44 ppm NO3-. Published: 2014-07-23, Updated: 2017-01-29, This article is based on an experiment by. Information from the experiment taken and the pictures used with the kind permission of the author. In both cases, it was able to break down all ammonia in 24 hours, but lagged with nitrite. Some people say it works, other people say it's doesn't at all . eheim substrat pro vs fluval g-nodes ... , (before clogging), bio-media. This also leads to disruption of mineralization and begining of humification, the products of which are mainly hard-to-decompose humins, humic acids and fulvic acids. The dose of 88 ppm NH3 was not able to completely break down (see day #19). Seachem Matrix vs pumice. An empty aquarium without filter, only with an air stone, could barely remove the dose of 4 ppm NH3. According to Seachem, 1 liter of their Matrix bio media gives you the same amount of surface area as 170 liters of plastic ball alternatives. This means that in an empty 100ℓ aquarium there are so many nitrifying bacteria that it would not be a problem for them to break down ammonia from 5,454 pcs of adult Neon Tetra Seachem's premise is matrix is pumice that has been tested for low reactivity to anything found in tropical fresh water or salt water tanks. This means all the surface area stays available for bacteria to use. In addition, nitrifying bacteria are able to multiply quite quickly, or only a relatively small amount of bacteria suffices to effectively remove even a relatively large amount of ammonia. Podle bezpečnostního listu od filtračního materiálu Seachem Matrix není toto filtrační médium ničím jiným než 100% pemzou. it can theoretically result in up to ~115 ppm of NO2- (45*2.55) or ~155 ppm of 3 NO3- (45*3.44). pumice. All times are GMT-5. The other eheim medias are not quite as good, less porosity, so you'd probably need more for equivalent performance. Ceramic rings will work equally as well, at a fraction of the price. You can get their Pond matrix in a 5.3 gallon bucket for like $100 and have enough to split between several people. Thus, both filter media seem to have the same nitrification capacity, which just confirms that it is the same material, i.e. Coarse Foam Weighted Base Can Install Air Stone Sponge filters offer reliability and hassle-free operation. Biofilm (slime) inside the filter before cleaning. During the previous experiment, it emerged that high doses of ammoniacal nitrogen led to an extreme increase in nitrate concentration, The dosage of 34.8 ppm any filter media did not completely break down in 25 hours. Unfortunately even though we do our best to carefully QC the product, it is a naturally mined media so sometimes anomalies occur. (which was previously removed and transferred to an empty filter in the Bare Tank aquarium) was inserted into the filter. That certainly explains the dust! While, after removing the filter media, the first aquarium has break down virtually the same amount of ammonia and nitrite as with the filter media 0.113 mℓ of filter media (0.17/1,500). 4ℓ of Seachem Matrix          = $31.80 The term pumice indicates many types of stone and they have different value for porosity or chemical property. I can easily rejig it anyway, at a later date, to see if there is any improvement in the flow rate etc. Of all the microorganisms involved in the decomposition of organic substances in the aquarium, nitrifying bacteria form only a negligible (though important) fraction. Or enough for 1 monster tank Pumice is a generic form of volcanic rock whose ingredients may vary. I noticed many users have complained about receiving an adulterated product, and frankly I thought I had received one as well. Assuming we have 100 pieces of adult Neon Tetra of 2 inches (5 cm) in length and 1.85 grams per piece in our aquarium (185 g in total), I use matrix now because when I started out using triton with marine pure, I saw small amounts of aluminum in my water from the ICP. This is actually a great advantage about this product. By all types of aquariums I mean ALL types. Conversely, if the nitrification would collapse after the removal of the filter media, it would mean that the filter media plays an important role. With no moving parts, all you need is an air supply and you've got a filter that is fully contained within your aquarium. Seachem Matrix is an aquarium conditioner aimed at people who need to either get rid of all the toxins in their aquarium water or for people who need to get their bacteria back. Note that it appears that Matrix was changed several years ago. Nitrification is the biological conversion of ammoniacal nitrogen (NH3/NH4+) to nitrites (NO2-), and subsequently to nitrates (NO3-). (calculated as 10G of water in aquarium + 2G water in filter = 12G = 45ℓ of water in total), Untreated tap water was put into the aquariums and the tanks were filtered (empty) for several days before the test was started. I noticed many users have complained about receiving an adulterated product, and frankly I thought I had received one as well. One person found this helpful. CDN$9.77. Helpful. Fluval Biomax = 12G = 45ℓ aquarium with Aquatop CF500UV filter without filter media. Filtration has several functions, of which nitrification (the biological conversion of ammoniacal nitrogen to nitrites and subsequently to nitrates) is only one of them. Seachem Matrix is a great natural medium for colonizing both nitrifying and denitrifying bacteria so important for good water chemistry and the health of one's aquarium inhabitants. No, I don't believe its better. (Since pumice comes from volcano's, it will have different properties (ingredients) depending on where it came from.) Matrix is very similar to the porous ceramic products in all its properties. One person found this helpful. The confusions start with the similarity in appearance of Matrix and garden center pumice. For comparison, I refer to a common pumice of various grain sizes: generalpumiceproducts.com. When you buy Matrix… Ammoniacal nitrogen is produced in the aquarium as a waste substance of some animals' metabolism and also in microbial decomposition of organic detritus. One liter of Matrix™ provides as much surface area (>700 square meters) as 170 … The time now is 01:19 AM. after adding these media back to the empty filter, the efficiency of nitrification in the second aquarium increased (the media helped to achieve better results). especially considering that even in an empty aquarium (with a filter without filter media) it can arise a large enough colony of nitrifying bacteria to break down an incredible 30 ppm of NH, Fish weight in aquarium: 185 g (100pcs * 1.85g), Daily feed dose: ~2 g (= 1% of body weight), Calculation: 2 * (23/100) * (16/100) * (61/100) * (1.216/1) = 2 * 0.23 * 0.16 * 0.61 * 1.216 = 0.055 g NH. 1ℓ of Seachem Matrix = $11.55 4ℓ of Seachem Matrix = $31.80 5ℓ of Pumice (Czech Republic) = $3 If the bacteria in the filter media could handle the given amount of ammonia in 24 hours without any problems, Seachem Matrix, 500ml/7.1-Ounce 4.5 out of 5 stars 247. Seachem Matrix is a great natural medium for colonizing both nitrifying and denitrifying bacteria so important for good water chemistry and the health of one's aquarium inhabitants. I also Googled "bulk pumice stone", and sure enough it looks just like Matrix. or perhaps there was no longer any additional place for NO3- in the tank). Of course, I do not question the need to remove dissolved organic substances, microscopic algae or other (fine) mechanical pollution from water. This page was generated at 21:12. The most effective filter medium in the degradation of ammonia (nitrification) has proved to be an ordinary foam filter called. Filter and aquarium after thorough cleaning. Is there a big difference between Marinepure balls vs matrix vs just using (dead/dry) rock rubble? Plus they both float - another giveaway. 7ℓ of Pumice (GeneralPumice)  = $25.00. Thus, a normal planted aquarium most likely does not need any biological filtration (at least not for ammonia removal), and the hype around the ever more perfect filters seems odd (unfounded) in the light of this experiment. Also it will never alter the pH of your aquarium. Top - Biological;Seachem Matrix + polishing pad to protect the impeller and motor I think it should work best like this as the biological media gets smaller as the baskets get nearer the top. But remember, not every porous stone is the same. Yes make sure you rise I bought a bucket 4liter of matrix and no where on the bucket does is say it needs rinsed but I did because I figured it would be best because of dust and maybe a few random rock luckily I did rinse because little did I know if I didn’t rinse I would have killed all my fish there was about 1 liter of the bucket that was not pumice and a little Suprise In there a bullet I have emailed seachem support Saturday and still am waiting a reply. Only 0.002% of all bacteria in the aquarium are nitrifying. or biological (microbial) decomposition of complex organic compounds into simpler compounds or elements (nutrients) → so-called mineralization. Whether the different types of aquarium filtration actually help in the mineralization itself (i.e. 5ℓ of Pumice (Czech Republic) =  $3 Bare Tank = 12G = 45ℓ aquarium with Eheim Pro II 2028 filter, which has 1ℓ of Fluval Biomax media (originally placed in Fluval Biomax aquarium). A small sponge filter (bubble blower) managed to break down an incredible dose of 70 ppm NH3 in 24 hours, Seachem Matrix on the other hand has less surface area due to the channels and pores being larger, but because they are larger they are not blocked by the bacteria. [Right aquarium.]. It turned out that even in an absolutely empty aquarium without plants, substrate and various filter media, enough bacteria will grow (reproduce) that are able to break down an incredible 30 ppm NH3 in 24 hours. It is good to maximize the filter stages in which the nitrifying and heterotrophic bacteria can grow. Any other pumice used would be unknown regarding safety. Ammonium itself (NH4+) is not toxic to fish, because fish as well as plants are capable of regulating its intake, unlike ammonia gas (NH3), The surface of the Matrix media provides a rough surface for bacterial attachment. Seachem Denitrate – and Seachem Matrix – can do a fantastic job of helping to lower the nitrates in your aquarium. The company claims that the conditioner controls ammonia, nitrite, and nitrate in an efficient way while still maintaining high capacity levels of biofiltration. For example, if 15 ppm NH4+ (= 45 ppm NH4+ in total) is added to water for 3 days in succession, The 3/8" size is the same as Seachem Matrix. The term pumice includes many types of stone and not all of them have the same porosity or same chemical makeup. It is extremely expensive with very little effective surface area (about 20 to 40 ft 2 /ft 3). 1 ppm NH3 = 2.70 ppm NO2- = 3.64 ppm NO3- Go with the best looking dead rock you can find for the display and use seachem pond sized matrix (or equivalent in other brands) in the sump for nitrification. Seachem Matrix Vs Pumice. Again, we sincerely apologize, and thanks for reaching out to us! Both filter media (Seachem Matrix as well as Pumice) managed to completely remove 30 ppm of ammoniacal nitrogen in 24 hours. which no other filter (or filter media) tested was able to manage (see day #18). detail of the cleaned compartments of the filter in the pictures above with the right image). 1ℓ of Seachem Matrix          = $11.55 If you want to use Matrix in an Aquaclear, I suggest to use the included foam sponge block in the bottom of the basket, and place the Matrix in a media bag. The experience of many aquarists suggests that some types of filters may act rather as organic waste producers in the aquarium instead of water purifiers. and therefore only a relatively small amount is needed to convert ammoniacal nitrogen to nitrite and nitrate. If 1ℓ of Seachem Matrix filter media has a surface area of 1,500 m2, then 0.17 m2 of surface area corresponds theoretically to just 0.000113ℓ, Testing of seachem matrix has shown that in some systems, anerobic bacteria capable of denitrofication colonize inside of matrix. From the results it can be seen that the empty filter without the filter media gave practically the same results at the dose of 46 ppm NH3 as with the filter media. Besides the fact that nitrification "takes a back seat" in the aquarium, nitrifying bacteria are moreover very effective "in their field" (or domain), Fluval Biomax = 12G = 45ℓ aquarium with Aquatop CF500UV filter, which has 1ℓ of Fluval Biomax as filter medium. It can be assumed that even some reasonably large increase in ammonia concentration (e.g. [Middle aquarium. I would have two of three of these baskets filled with it. However, filtration may have other useful functions in the aquarium, such as mechanical removal of fine particles from water, chemical absorption and adsorption of harmful molecules into the resin or other filter media, And once I … The results in this case are not entirely clear. According to the safety data sheet of the Seachem Matrix filter media, this filter medium is nothing but 100% pumice. (, An empty aquarium with a filter without filter media can break down at least the same amount of ammoniacal nitrogen as an aquarium with a handful of high-quality filter media (.
