Matrix is very similar to the porous ceramic products in all its properties. Few, however, know that nitrification is only the tip of the iceberg in different kinds of decomposition processes. What you want to do is clean them under softly running water that’s around room temperature. 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, If all the filter media was removed from the Aquatop filter, and yet it was able to break down most of the ammonia, Helpful. The surface of the Matrix media provides a rough surface for bacterial attachment. I can easily rejig it anyway, at a later date, to see if there is any improvement in the flow rate etc. Biofilm (slime) inside the filter before cleaning. One person found this helpful. or biological (microbial) decomposition of complex organic compounds into simpler compounds or elements (nutrients) → so-called mineralization. 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. 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. Thank you for visiting the Seachem Support and Discussions Board. The goal of this test was to find out what share in the total nitrification the filter media themselves have. 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 The 3/8" size is the same as Seachem Matrix. Author of the test: Linn Fahrenkrug (Immortal1) from Iowa, USA. This usually means to have a very porous filter media. Thank you for getting in touch with our support team about this. 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). Podle bezpečnostního listu od filtračního materiálu Seachem Matrix není toto filtrační médium ničím jiným než 100% pemzou. 1ℓ of Seachem Matrix = $11.55 4ℓ of Seachem Matrix = $31.80 5ℓ of Pumice (Czech Republic) = $3 [Middle aquarium. Again, we sincerely apologize, and thanks for reaching out to us! 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 (, 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 (. Plus they both float - another giveaway. it can theoretically result in up to ~115 ppm of NO2- (45*2.55) or ~155 ppm of 3 NO3- (45*3.44). i.e. According to the safety data sheet of the Seachem Matrix filter media, this filter medium is nothing but 100% pumice. 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. Another experiment that was not done by me, but by one American aquarist who gave me permission to describe it here. One liter of Matrix™ provides as much surface area (>700 square meters) as 170 … So then I Googled "Matrix pumice" and found another forum conversation where the same thing was said. One person found this helpful. Matrix is made out of refined pumice stone . For comparison, I refer to a common pumice of various grain sizes: generalpumiceproducts.com. In both cases, it was able to break down all ammonia in 24 hours, but lagged with nitrite. 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. If the bacteria in the filter media could handle the given amount of ammonia in 24 hours without any problems, A complete filter media (= 1ℓ) was removed from the Fluval Biomax aquarium and moved to the Bare Tank. Sorry, the board is unavailable at the moment for maintenance. Fluval Biomax = 12G = 45ℓ aquarium with Aquatop CF500UV filter, which has 1ℓ of Fluval Biomax as filter medium. 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), According to the safety data sheet of the Seachem Matrix filter media, this filter medium is nothing but 100% pumice. The most effective filter medium in the degradation of ammonia (nitrification) has proved to be an ordinary foam filter called. Of all the microorganisms involved in the decomposition of organic substances in the aquarium, nitrifying bacteria form only a negligible (though important) fraction. It is good to maximize the filter stages in which the nitrifying and heterotrophic bacteria can grow. This is the second item that’s worth checking out. It is extremely expensive with very little effective surface area (about 20 to 40 ft 2 /ft 3). 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. The filters compete with plants because some nutrients can often precipitate in them (most often iron and phosphorus). 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. 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. The effect of bacteria mixtures in aquarium cycling, [Leftmost aluminium basin (volume approx. Only 0.002% of all bacteria in the aquarium are nitrifying. (which was previously removed and transferred to an empty filter in the Bare Tank aquarium) was inserted into the filter. 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. It has a much higher surface area than most live rock. … Seachem Denitrate – and Seachem Matrix – can do a fantastic job of helping to lower the nitrates in your aquarium. So I have 2 questions; (sorry for the thread hijack!) Warning: Matrix is pumice rock You can . 4ℓ of Seachem Matrix          = $31.80 Also it will never alter the pH of your aquarium. Testing of seachem matrix has shown that in some systems, anerobic bacteria capable of denitrofication colonize inside of matrix. dead fish decaying somewhere unnoticed) may not pose any problem for an already established colony of nitrifying bacteria, 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. The company claims that the conditioner controls ammonia, nitrite, and nitrate in an efficient way while still maintaining high capacity levels of biofiltration. Dumping loose pumice rocks into the basket will be a royal PITA when it's time to clean the filter. [Right aquarium.]. Bare Tank = 12G = 45ℓ aquarium with Eheim Pro II 2028 filter, which has 1ℓ of Fluval Biomax media (originally placed in Fluval Biomax aquarium). 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. 6.5G = 25ℓ).]. 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 pond matrix 4l Box Contains. 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. 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. Is there a big difference between Marinepure balls vs matrix vs just using (dead/dry) rock rubble? Seachem Matrix, 500ml/7.1-Ounce 4.5 out of 5 stars 247. It can be assumed that even some reasonably large increase in ammonia concentration (e.g. Filter and aquarium after thorough cleaning. 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 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. Note that it appears that Matrix was changed several years ago. An empty aquarium (Bare Tank), which, without filter media, was able to completely remove 30.6 ppm of NH3 at most in 24 hours, Well, isn't it interesting - lol. suggesting that the filter media provide at least a comparable colonizing area as the removed biofilm. during the whole experiment (see the next picture). Matrix™ is a specific type chosen for its extremely high porosity, pore size, durability, and inert nature. 1ℓ of Seachem Matrix          = $11.55 Nitrification is the biological conversion of ammoniacal nitrogen (NH3/NH4+) to nitrites (NO2-), and subsequently to nitrates (NO3-). Hello Jmacke! 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. it is important to often change large amounts of water. This is actually a great advantage about this product. ... 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. Aerobic microbes are needed to convert ammoniacal nitrogen to nitrites and subsequently to nitrates. A small sponge filter (bubble blower) managed to break down an incredible dose of 70 ppm NH3 in 24 hours, I called Seachem and got the scoop. In my point of view, the stuff from Seachem for that is the best one. 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. 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. 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 … (which would clearly indicate that the filter media have virtually no effect on the nitrification efficiency), Ceramic rings will work equally as well, at a fraction of the price. The rest (99.998%) belongs to heterotrophic bacteria. An empty aquarium without filter, only with an air stone, could barely remove the dose of 4 ppm NH3. Amazon usually has 1-liter containers of Matrix for around $11. 1. The term pumice indicates many types of stone and they have different value for porosity or chemical property. All times are GMT-5. The dosage of 34.8 ppm any filter media did not completely break down in 25 hours. which no other filter (or filter media) tested was able to manage (see day #18). Seachem Matrix Biological Media. 1ℓ Seachem Matrix = 500,- Kč Subsequently, 16 ppm of NH3 was added to the water. Porozitate redusa inseamna mai putine bacterii ( ni si deni - … 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. Published: 2014-07-23, Updated: 2017-01-29, This article is based on an experiment by. The importance of filtration (or filter media) appears to be overestimated (at least in terms of nitrification). Pumice is a generic form of volcanic rock whose ingredients may vary. With Matrix, you are assured to not leach anything in your tank water. 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). Some people say it works, other people say it's doesn't at all . 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. That certainly explains the dust! 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. and subsequent proliferation of algae, are (given the enormous nitrification capacity of the empty aquarium) most likely nonsense. 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. The results in this case are not entirely clear. it would mean that the filter media account for at least 50% of the total nitrification. Yes most porous media will promte some growth of anaerobic over time. Matrix is a solid pumice biomedia processed to form 10-mm pebbles. Pro srovnání uvádím odkaz na obyčejnou pemzu o různé zrnitosti: generalpumiceproducts.com. (or 10 kg of well fed fish). By all types of aquariums I mean ALL types. production of toxic compounds). 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. 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. which intake the fish and plants can't control, and is therefore potentially much more toxic to them. Ammoniacal nitrogen is produced in the aquarium as a waste substance of some animals' metabolism and also in microbial decomposition of organic detritus. Next criteria is the size of pores in the medium. Its much simpler, safer, and cheaper than bringing in that beautiful live rock at a very high price and a lot of nasty critters. In the aquarium hobby, the idea (or rather the myth) spread that for the removal of ammoniacal nitrogen (NH3/NH4+) from the aquarium water Seachem Matrix. Unfortunately even though we do our best to carefully QC the product, it is a naturally mined media so sometimes anomalies occur. The dose of 88 ppm NH3 was not able to completely break down (see day #19). No Filter (aquarium w/o filter) = 12G = 45ℓ aquarium without filter, only with an air stone. 200%) si deci si porozitatea ar trebui sa difere mult. I noticed many users have complained about receiving an adulterated product, and frankly I thought I had received one as well. Sponge = 12G = 45ℓ aquarium with inner sponge filter (designed for 20G = 75ℓ aquarium). No, I don't believe its better. It is also quite possible that many filters may increase ammonium concentration in the aquarium rather than reduce it effectively. For an idea: This amount of ammonia is produced by more than 10 kg of adult Neon Tetras in 24 hours. 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 Increased concentrations of dissolved organic matter in the water can then promote the growth of some algae. 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. Pumice stone is super porous and is supposed to be able to harbor denitrifying bacteria inside anaerobic areas deep inside the pumice stone . or perhaps there was no longer any additional place for NO3- in the tank). 1 ppm NH3 = 2.70 ppm NO2- = 3.64 ppm NO3- This test should verify if most of the nitrifying bacteria were concentrated in the filter medium or is located elsewhere (e.g. Years ago Matrix was obviously pumice, a type of volcanic rock which doesn’t absorb water and floats. (cf. You can get their Pond matrix in a 5.3 gallon bucket for like $100 and have enough to split between several people. Read more. This means all the surface area stays available for bacteria to use. Of course, I do not question the need to remove dissolved organic substances, microscopic algae or other (fine) mechanical pollution from water. on filter walls, in hoses, and the like). 1 ppm NH4+ = 2.55 ppm NO2- = 3.44 ppm NO3-. 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, 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. 5ℓ of Pumice (Czech Republic) =  $3 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 Any other pumice used would be unknown regarding safety. With no moving parts, all you need is an air supply and you've got a filter that is fully contained within your aquarium. Filtration has several functions, of which nitrification (the biological conversion of ammoniacal nitrogen to nitrites and subsequently to nitrates) is only one of them. Consequently, with high production of ammoniacal nitrogen, nitrates will accumulate to a large extent in the aquarium Conversely, if the nitrification would collapse after the removal of the filter media, it would mean that the filter media plays an important role. I noticed many users have complained about receiving an adulterated product, and frankly I thought I had received one as well. they need less than 5 g of food per day. 7ℓ of Pumice (GeneralPumice)  = $25.00. Regarding nitrification, it seems to be proven that filtration (or filter media) is superfluous in a normal, well-functioning planted aquarium. When you buy Matrix… It's hard to blame marine pure directly because this could have been from PVC or something else. 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. CDN$9.77. With Matrix, you know it isn’t going to affect your pH or leach anything into your tank. (Since pumice comes from volcano's, it will have different properties (ingredients) depending on where it came from.) Then 46 ppm of NH3 was added to both aquariums again. The Planted Tank Forum > Specific Aspects of a Planted Tank > Equipment > Best Biological Media 4 Filter - Seachem Matrix vs Fluval BioMax Reply. (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. 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). Bare Tank (empty aquarium) = 45ℓ aquarium with Eheim Pro II 2028 filter without filter media. The other eheim medias are not quite as good, less porosity, so you'd probably need more for equivalent performance. Seachem Matrix vs pumice. /';this should keep you in media for years. Or enough for 1 monster tank Besides the fact that nitrification "takes a back seat" in the aquarium, nitrifying bacteria are moreover very effective "in their field" (or domain), Day # 19 ) a normal, well-functioning planted aquarium to figure this out has been processed 10mm!
