It’s a very porous media that provides excellent biological filtration in all types of aquariums. Hello Jmacke! One person found this helpful. . What you want to do is clean them under softly running water that’s around room temperature. Of course, I do not question the need to remove dissolved organic substances, microscopic algae or other (fine) mechanical pollution from water. Amazon usually has 1-liter containers of Matrix for around $11. BigXor. 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 Next criteria is the size of pores in the medium. With no moving parts, all you need is an air supply and you've got a filter that is fully contained within your aquarium. Matrix™ is a specific type chosen for its extremely high porosity, pore size, durability, and inert nature. Regarding nitrification, it seems to be proven that filtration (or filter media) is superfluous in a normal, well-functioning planted aquarium. /';this should keep you in media for years. Subsequently, 16 ppm of NH3 was added to the water. was able to remove up to 46 ppm of NH3 with the added filter media. Matrix is very similar to the porous ceramic products in all its properties. Any other pumice used would be unknown regarding safety. Conversely, if the nitrification would collapse after the removal of the filter media, it would mean that the filter media plays an important role. it is important to often change large amounts of water. 1ℓ of Seachem Matrix          = $11.55 With Matrix, you are assured to not leach anything in your tank water. Information from the experiment taken and the pictures used with the kind permission of the author. It is good to maximize the filter stages in which the nitrifying and heterotrophic bacteria can grow. Whether the different types of aquarium filtration actually help in the mineralization itself (i.e. This is the second item that’s worth checking out. Some people say it works, other people say it's doesn't at all . 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 That certainly explains the dust! Matrix is made out of refined pumice stone . it would mean that the filter media account for at least 50% of the total nitrification. Sponge = 12G = 45ℓ aquarium with inner sponge filter (designed for 20G = 75ℓ aquarium). Seachem Matrix, 500ml/7.1-Ounce 4.5 out of 5 stars 247. Few, however, know that nitrification is only the tip of the iceberg in different kinds of decomposition processes. I also Googled "bulk pumice stone", and sure enough it looks just like Matrix. When I switched to matrix I didn't have the problem anymore. … 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). Thank you for visiting the Seachem Support and Discussions Board. which no other filter (or filter media) tested was able to manage (see day #18). Well, isn't it interesting - lol. Ammonium itself (NH4+) is not toxic to fish, because fish as well as plants are capable of regulating its intake, unlike ammonia gas (NH3), 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, pumice. Pumice is a generic form of volcanic rock whose ingredients may vary. You can get their Pond matrix in a 5.3 gallon bucket for like $100 and have enough to split between several people. 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. or biological (microbial) decomposition of complex organic compounds into simpler compounds or elements (nutrients) → so-called mineralization. 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. Seachem Matrix vs pumice. With Matrix, you know it isn’t going to affect your pH or leach anything into your tank. One liter of Matrix™ provides as much surface area (>700 square meters) as 170 … A high concentration of ammoniacal nitrogen results in an increase in nitrite concentration, which is converted by bacteria into nitrates. I can easily rejig it anyway, at a later date, to see if there is any improvement in the flow rate etc. Again, we sincerely apologize, and thanks for reaching out to us! and subsequent proliferation of algae, are (given the enormous nitrification capacity of the empty aquarium) most likely nonsense. 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. 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. One person found this helpful. 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. It's hard to blame marine pure directly because this could have been from PVC or something else. (cf. it is necessary to use a good biological filter with a large colonizing area for a sufficiently large colony of nitrifying microbes. It has a rough surface, which is perfect for bacteria. In both cases, it was able to break down all ammonia in 24 hours, but lagged with nitrite. suggesting that the filter media provide at least a comparable colonizing area as the removed biofilm. I noticed many users have complained about receiving an adulterated product, and frankly I thought I had received one as well. i.e. Read more. 1. The Seachem Matrix is a bio media made of solid pumice that has been processed into 10mm pebbles. Then 46 ppm of NH3 was added to both aquariums again. 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 [Right aquarium.]. 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, For comparison, I refer to a common pumice of various grain sizes: generalpumiceproducts.com. 5ℓ of Pumice (Czech Republic) =  $3 (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. 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. 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. Yes most porous media will promte some growth of anaerobic over time. Note that it appears that Matrix was changed several years ago. 1 ppm NH4+ = 2.55 ppm NO2- = 3.44 ppm NO3-. 4ℓ of Seachem Matrix          = $31.80 Warning: The other eheim medias are not quite as good, less porosity, so you'd probably need more for equivalent performance. On Saturday, the filter was thoroughly cleaned and only 3 days later it was again covered with a continuous layer of biofilm 6.5G = 25ℓ).]. 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. seachem pond matrix 4l Box Contains. Specifically designed for the Fluval U2/U3/U4 filters, BIOMAX provides an optimal environment for the colonization and growth of beneficial bacteria. Seachem are great marketers, but not always that great when it comes to providing actual scientific data to back up their claims. 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). Pro srovnání uvádím odkaz na obyčejnou pemzu o různé zrnitosti: generalpumiceproducts.com. 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 rest (99.998%) belongs to heterotrophic bacteria. (Since pumice comes from volcano's, it will have different properties (ingredients) depending on where it came from.) 0.113 mℓ of filter media (0.17/1,500). Seachem Matrix Biological Media. No Filter (aquarium w/o filter) = 12G = 45ℓ aquarium without filter, only with an air stone. 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. But for this purpose, I think it is preferable to use activated carbon in combination with some fine mechanical filtration. I called Seachem and got the scoop. 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. The importance of filtration (or filter media) appears to be overestimated (at least in terms of nitrification). Seachem Matrix. This is actually a great advantage about this product. The effect of bacteria mixtures in aquarium cycling, [Leftmost aluminium basin (volume approx. The confusions start with the similarity in appearance of Matrix and garden center pumice. 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, 1ℓ of Seachem Matrix = $11.55 4ℓ of Seachem Matrix = $31.80 5ℓ of Pumice (Czech Republic) = $3 Author of the test: Linn Fahrenkrug (Immortal1) from Iowa, USA. Note: Pond matrix is the same as matrix just bigger pieces. Is there a big difference between Marinepure balls vs matrix vs just using (dead/dry) rock rubble? 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. asked on February 13, 2013. When you buy Matrix… during the whole experiment (see the next picture). 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. on filter walls, in hoses, and the like). 7ℓ of Pumice (GeneralPumice)  = $25.00. Thank you for getting in touch with our support team about this. It is extremely expensive with very little effective surface area (about 20 to 40 ft 2 /ft 3).
