For comparison, I refer to a common pumice of various grain sizes: generalpumiceproducts.com. BigXor. asked on February 13, 2013. 1 ppm NH3 = 2.70 ppm NO2- = 3.64 ppm NO3- (up to 76 ppm of NO. By all types of aquariums I mean ALL types. It took me 6 months to figure this out. 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. Matrix is a solid pumice biomedia processed to form 10-mm pebbles. 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. Its much simpler, safer, and cheaper than bringing in that beautiful live rock at a very high price and a lot of nasty critters. Nitrification is the biological conversion of ammoniacal nitrogen (NH3/NH4+) to nitrites (NO2-), and subsequently to nitrates (NO3-). Or enough for 1 monster tank The day before the test, water was treated with. It can be assumed that even some reasonably large increase in ammonia concentration (e.g. The goal of this test was to find out what share in the total nitrification the filter media themselves have. Seachem Matrix vs pumice. I also Googled "bulk pumice stone", and sure enough it looks just like Matrix. Information from the experiment taken and the pictures used with the kind permission of the author. 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. Subsequently, 16 ppm of NH3 was added to the water. Thank you for getting in touch with our support team about this. Of course, I do not question the need to remove dissolved organic substances, microscopic algae or other (fine) mechanical pollution from water. eheim substrat pro vs fluval g-nodes ... , (before clogging), bio-media. The effect of bacteria mixtures in aquarium cycling, [Leftmost aluminium basin (volume approx. 1ℓ Seachem Matrix = 500,- Kč Bare Tank = 12G = 45ℓ aquarium with Eheim Pro II 2028 filter, which has 1ℓ of Fluval Biomax media (originally placed in Fluval Biomax aquarium). Matrix™ is a specific type chosen for its extremely high porosity, pore size, durability, and inert nature. … dead fish decaying somewhere unnoticed) may not pose any problem for an already established colony of nitrifying bacteria, it would mean that the filter media account for at least 50% of the total nitrification. Note that it appears that Matrix was changed several years ago. The surface of the Matrix media provides a rough surface for bacterial attachment. Dumping loose pumice rocks into the basket will be a royal PITA when it's time to clean the filter. According to the safety data sheet of the Seachem Matrix filter media, this filter medium is nothing but 100% pumice. 200%) si deci si porozitatea ar trebui sa difere mult. 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). No, I don't believe its better. Ammoniacal nitrogen is produced in the aquarium as a waste substance of some animals' metabolism and also in microbial decomposition of organic detritus. Conversely, if the nitrification would collapse after the removal of the filter media, it would mean that the filter media plays an important role. ... 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. 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). 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, (, 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 (. This is the second item that’s worth checking out. I noticed many users have complained about receiving an adulterated product, and frankly I thought I had received one as well. 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. Ammonium itself (NH4+) is not toxic to fish, because fish as well as plants are capable of regulating its intake, unlike ammonia gas (NH3), Porozitate redusa inseamna mai putine bacterii ( ni si deni - … I would have two of three of these baskets filled with it. In my point of view, the stuff from Seachem for that is the best one. it can theoretically result in up to ~115 ppm of NO2- (45*2.55) or ~155 ppm of 3 NO3- (45*3.44). Seachem Matrix is nothing more than expensive pumice stone. Few, however, know that nitrification is only the tip of the iceberg in different kinds of decomposition processes. 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. But for this purpose, I think it is preferable to use activated carbon in combination with some fine mechanical filtration. Thus, both filter media seem to have the same nitrification capacity, which just confirms that it is the same material, i.e. Both filter media (Seachem Matrix as well as Pumice) managed to completely remove 30 ppm of ammoniacal nitrogen in 24 hours. 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. i.e. Sponge = 12G = 45ℓ aquarium with inner sponge filter (designed for 20G = 75ℓ aquarium). Helpful. A high concentration of ammoniacal nitrogen results in an increase in nitrite concentration, which is converted by bacteria into nitrates. Hello Jmacke! So I have 2 questions; (sorry for the thread hijack!) Besides the fact that nitrification "takes a back seat" in the aquarium, nitrifying bacteria are moreover very effective "in their field" (or domain), Note: Pond matrix is the same as matrix just bigger pieces. The other eheim medias are not quite as good, less porosity, so you'd probably need more for equivalent performance. Author of the test: Linn Fahrenkrug (Immortal1) from Iowa, USA. 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. 5ℓ of Pumice (Czech Republic) =  $3 (cf. pumice. 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. was able to remove up to 46 ppm of NH3 with the added filter media. It is … Matrix certainly isn't the only biomedia you can choose. Un material mucho más efectivo en filtración biologica de acuarios. 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. According to the safety data sheet of the Seachem Matrix filter media, this filter medium is nothing but 100% pumice. production of toxic compounds). For comparison, I refer to a common pumice of various grain sizes: generalpumiceproducts.com. during the whole experiment (see the next picture). 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. The term pumice includes many types of stone and not all of them have the same porosity or same chemical makeup. All times are GMT-5. it is important to often change large amounts of water. When you buy Matrix… Some people say it works, other people say it's doesn't at all . 1 ppm NH4+ = 2.55 ppm NO2- = 3.44 ppm NO3-. A complete filter media (= 1ℓ) was removed from the Fluval Biomax aquarium and moved to the Bare Tank. The time now is 01:19 AM. Consequently, with high production of ammoniacal nitrogen, nitrates will accumulate to a large extent in the aquarium Any other pumice used would be unknown regarding safety. Seachem Matrix Biological Media. For an idea: This amount of ammonia is produced by more than 10 kg of adult Neon Tetras in 24 hours. It's hard to blame marine pure directly because this could have been from PVC or something else. The filters compete with plants because some nutrients can often precipitate in them (most often iron and phosphorus). For example, if 15 ppm NH4+ (= 45 ppm NH4+ in total) is added to water for 3 days in succession, Only 0.002% of all bacteria in the aquarium are nitrifying. CDN$9.77. It has a rough surface, which is perfect for bacteria. 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. I can easily rejig it anyway, at a later date, to see if there is any improvement in the flow rate etc. Coarse Foam Weighted Base Can Install Air Stone Sponge filters offer reliability and hassle-free operation. 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. Pro srovnání uvádím odkaz na obyčejnou pemzu o různé zrnitosti: generalpumiceproducts.com. But remember, not every porous stone is the same. Biofilm (slime) inside the filter before cleaning. Whether the different types of aquarium filtration actually help in the mineralization itself (i.e. Warning: 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. Testing of seachem matrix has shown that in some systems, anerobic bacteria capable of denitrofication colonize inside of matrix. and subsequent proliferation of algae, are (given the enormous nitrification capacity of the empty aquarium) most likely nonsense. The 3/8" size is the same as Seachem Matrix. But there is one very simple, yet important step you must take in order to unlock their full potential. It is also quite possible that many filters may increase ammonium concentration in the aquarium rather than reduce it effectively. Some filters may function as "traps" and producers rather than "degraders" of organic waste. 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. 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. This test should verify if most of the nitrifying bacteria were concentrated in the filter medium or is located elsewhere (e.g. With Matrix, you are assured to not leach anything in your tank water. One person found this helpful. During the previous experiment, it emerged that high doses of ammoniacal nitrogen led to an extreme increase in nitrate concentration, 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 rest (99.998%) belongs to heterotrophic bacteria. 1ℓ of Seachem Matrix          = $11.55 or perhaps there was no longer any additional place for NO3- in the tank). Seachem Matrix vs. pemza. This is actually a great advantage about this product. The company claims that the conditioner controls ammonia, nitrite, and nitrate in an efficient way while still maintaining high capacity levels of biofiltration. Seachem are great marketers, but not always that great when it comes to providing actual scientific data to back up their claims. 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, or biological (microbial) decomposition of complex organic compounds into simpler compounds or elements (nutrients) → so-called mineralization. . 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 When I switched to matrix I didn't have the problem anymore. An empty aquarium (Bare Tank), which, without filter media, was able to completely remove 30.6 ppm of NH3 at most in 24 hours, 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. Any questions posted over the weekend will be addressed the following Monday. 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). 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. Seachem Denitrate – and Seachem Matrix – can do a fantastic job of helping to lower the nitrates in your aquarium. And once I … A: We certainly understand why people look at Matrix™ and compare it to pumice; they are both porous stones. 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, [Right aquarium.]. What you want to do is clean them under softly running water that’s around room temperature. Filtration has several functions, of which nitrification (the biological conversion of ammoniacal nitrogen to nitrites and subsequently to nitrates) is only one of them. It has a much higher surface area than most live rock. It is extremely expensive with very little effective surface area (about 20 to 40 ft 2 /ft 3). /';this should keep you in media for years. it would mean that the filler itself does not play very important role in the nitrification. 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. it is necessary to use a good biological filter with a large colonizing area for a sufficiently large colony of nitrifying microbes. seachem pond matrix 4l Box Contains. Increased concentrations of dissolved organic matter in the water can then promote the growth of some algae. 7ℓ of Pumice (GeneralPumice)  = $25.00. Published: 2014-07-23, Updated: 2017-01-29, This article is based on an experiment by. The dosage of 34.8 ppm any filter media did not completely break down in 25 hours. It is good to maximize the filter stages in which the nitrifying and heterotrophic bacteria can grow. detail of the cleaned compartments of the filter in the pictures above with the right image). One liter of Matrix™ provides as much surface area (>700 square meters) as 170 … Podle bezpečnostního listu od filtračního materiálu Seachem Matrix není toto filtrační médium ničím jiným než 100% pemzou. If all the filter media was removed from the Aquatop filter, and yet it was able to break down most of the ammonia, 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 and therefore only a relatively small amount is needed to convert ammoniacal nitrogen to nitrite and nitrate. Of all the microorganisms involved in the decomposition of organic substances in the aquarium, nitrifying bacteria form only a negligible (though important) fraction. Seachem Matrix Vs Pumice. Is there a big difference between Marinepure balls vs matrix vs just using (dead/dry) rock rubble? (which was previously removed and transferred to an empty filter in the Bare Tank aquarium) was inserted into the filter. 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. One person found this helpful. 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. on filter walls, in hoses, and the like). Again, we sincerely apologize, and thanks for reaching out to us! Well, isn't it interesting - lol. Thank you for visiting the Seachem Support and Discussions Board. 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. 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. The confusions start with the similarity in appearance of Matrix and garden center pumice. which no other filter (or filter media) tested was able to manage (see day #18). The results in this case are not entirely clear. Then 46 ppm of NH3 was added to both aquariums again. 0.113 mℓ of filter media (0.17/1,500). So then I Googled "Matrix pumice" and found another forum conversation where the same thing was said. 6.5G = 25ℓ).]. (Since pumice comes from volcano's, it will have different properties (ingredients) depending on where it came from.) With no moving parts, all you need is an air supply and you've got a filter that is fully contained within your aquarium. Specifically designed for the Fluval U2/U3/U4 filters, BIOMAX provides an optimal environment for the colonization and growth of beneficial bacteria. Fluval Biomax = 12G = 45ℓ aquarium with Aquatop CF500UV filter without filter media. Fluval Biomax = 12G = 45ℓ aquarium with Aquatop CF500UV filter, which has 1ℓ of Fluval Biomax as filter medium. Regarding nitrification, it seems to be proven that filtration (or filter media) is superfluous in a normal, well-functioning planted aquarium. they need less than 5 g of food per day. The Seachem Matrix is a bio media made of solid pumice that has been processed into 10mm pebbles. An empty aquarium without filter, only with an air stone, could barely remove the dose of 4 ppm NH3. The term pumice indicates many types of stone and they have different value for porosity or chemical property. suggesting that the filter media provide at least a comparable colonizing area as the removed biofilm. 1. [Middle aquarium. You can get their Pond matrix in a 5.3 gallon bucket for like $100 and have enough to split between several people. 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. The most effective filter medium in the degradation of ammonia (nitrification) has proved to be an ordinary foam filter called. Unfortunately even though we do our best to carefully QC the product, it is a naturally mined media so sometimes anomalies occur. 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 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. 4ℓ of Seachem Matrix          = $31.80 This usually means to have a very porous filter media. The dose of 88 ppm NH3 was not able to completely break down (see day #19). 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. Matrix is pumice rock You can . Read more. This means all the surface area stays available for bacteria to use. 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. 1ℓ of Seachem Matrix = $11.55 4ℓ of Seachem Matrix = $31.80 5ℓ of Pumice (Czech Republic) = $3 With Matrix, you know it isn’t going to affect your pH or leach anything into your tank.
