I might only be adding 5 ml or a teaspoon per 100 litres but think to myself it’s one more change in parameters? I'll see how much I can get in there but I should be close to the 2.88 lbs I would need with 2 lbs/25 gallons I think. If Matrix™ is doing the job for you (i.e. For optimum biofilter performance use 1 capful for each 80 L (20 US gallons) once a month or with each water change and whenever introducing new fish or whenever medicating an aquarium. Now I know this includes the actual plastic container, but it can't weigh more than an oz or so. I am going with seachem pond matrix for the bio media. Seachem provides dosing instructions on all of our products, so you can always determine the correct dosage, but now it's even easier. Matrix™ is sufficiently large that no filter bag should be required for most applications. The filters are cleaned every 2-3 months (. I wouldn't get to caught up as to what Seachem recommends for the amount of Matrix per volume of tank. Seems weird to me as well. A: Nothing’s wrong. Matrix™ is a poreus nie Than the other 2 I would fill with bio media (matrix,biohome,pot scubbers...). If you need to use a higher flow rate, than stick with Matrix™ or try Pond Matrix™, both of which support anaerobic denitrification at higher flow rates. Matrix™ is compatible with all types of wet or wet-dry filters. If you have a freshwater tank, you should also add 2 tablespoons of buffer (Seachem suggest using Discus Buffer or Neutral Regulator). I can't say enough good things about this. Oh I agree there but for large setups I don't think the Matrix as Seachem Matrix and the price it sells at versus what else you can use is worth using in a whole big setup As you say, pumice does the same and I am sure much cheaper.. That’s my logic. After all of that, the Purigen will then be completely regenerated. I think your 306 has 3 chambers. After 24 hours, Purigen should turn whiter by now. That said it is possible for Matrix™ media to become clogged up with detritus and slime, so we recommend regular filter maintenance to ensure it continues working as efficiently as possible. However, it will help maintain your nitrates at lower levels. I would expect it to be a little bit different but almost double seems like it's got to be a misprint. I am setting up a Fluval 306 filter for my new 36 gallon bowfront and I'm a little uncertain about how much Seachem Matrix to use. Less dense is more porous, which would be beneficial, not detrimental. Plastic bio-materials provide only external surface area, whereas Matrix™ provides both external and internal macroporous surface area. Matrix™ is completely inert and will not breakdown. Matrix™ works well in drip tray systems, but you may find that the larger Pond Matrix™ is better suited for such applications. The same applies to nitrate removal. Won't be the first time Seachem has been wrong. Matrix™ has some natural variations in color and size of the pieces, ranging from very light to quite dark. Plas It you watch the videos on the subject you will see the media has large pour structure on the outside and more dense structure on the inside. My question is what is the difference between Seachem Matrix and Purigen? A: If you have a fish load it would be extremely difficult to bring down your nitrates to zero (fish foods, waste being introduced on a daily basis). Sizes: 100 mL, 250 mL, 500 mL, 1 L, 2 L, 4 L If you have enough media in your tank that the bacteria is eating the. Have planted 15,30 and 90 and they take a little more time to keep up. Matrix™ is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Thank you. Or how would you tell the difference? I would love a little "water polishing" too. Consult your filter’s instruction manual to find the direction of flow for your filter. I use a 30 gallon sump with bio-balls on a 5 foot 100 gallon tank. Ask us a new question. The removal of nitrates essentially comes down to one parameter: rate. you can use less de❊nitrate by volume than Matrix™ to get the same denitrifying capacity). A: Matrix™ is a biomedia, meaning it does not exhaust over time, so you should never need to replace it. Than the other 2 I would fill with bio media (. Matrix™ is a porous inorganic solid about 10 mm in diameter. Heck, you can see through them. Whether plants do it or bacteria, the cycle is still a cycle in that the nitrogen introduced has left the water column. But who knows, its only been a year, maybe the system will crash any day. Each liter of Matrix provides as much surface (<162 m) as 40 liters of plastic balls! Hmm. They actually fixed them the same day. Make sure to use bleach that doesn’t have anything extra such as scented or dye. Weird. Based on updated studies, we've found Matrix™ treats even more water than previously asserted. The directions says use 1 capful (5mL) for each 200 L (50 gallons) of new water. I would also put a sponge over the intake. Unless your tank is producing more than 40ppm of, Ok what I don’t understand is the reason to want denitrifying bacteria. You need for 4 tablespoons of Prime or 16 grams of Safe for every cup of water. 1mL). I looked at the Seachem websight and it states 250ml for 50 US gallons. Usage of content from this website is only intended for authorized distributors and sellers, and by individuals for private use. Green: There is no interaction between this product and Matrix™ Me I would make the first(lowest in canister) a corse than a fine sponge. Now for the actual use. Matrix™ may be placed in any kind of filter, and is particularly effective in a canister filter. The best way to check is to try it. Use in a filter bag. Thanks, Great video. The surface area that Seachem offers with their matrix product range about 700 m2/L, this can be a pretty large surface when compared to the competition, but another important thing to note is that the conditioner is efficient for both the interior and exterior of … This seems to be the principle on what a denitrifying reactor is based. Unless your tank is producing more than 40ppm of nitrate between, Who knew this question would evoke such a debate. At first I thought there's no way I could get that in my filter, but then I plopped my 2L container on my postal scale and it weighs 3.2 lbs. But remember, not every porous stone is the same. This allows Matrix™, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter. You aren't just purchasing the physical material when you buy a container of Matrix; you are purchasing the research which has sourced and tested this specific type of stone, and the assurance that it is safe for use in your aquarium.
