de*Nitrate 1 L / 61 cu.in.

Good product have used it for yrs. Doesn’t lower the nitrate in my salt water tank. After a week u should see a drop in it if u use enough.

Fantastic product! Eliminated the nitrites and nitrates completely within the first few days.

Just added to canister filter so idk how well it will work

Trabaja lento pero hace su trabajo

I started loosing fish in my 25 gal. Fish tank...checked my water and nitrates were way too high. Bought these white covered rocks and replaced my filter rocks for these...next day, happy and living fish again!!! I l9ve this product!!

I have been fighting a losing battle with the nitrates in my 75 gallon tank for over a month. I was about to lose my mind because nitrates remained around 80 ppm and I was losing fish almost daily. Last weekend I cleaned the canister filter, added half a liter of Denitrate, and did an 80% water change. I lost 3 fish in the meantime because the irreversible damage had already been done but now, a week later, my nitrates have been cut in half and the remaining fish are all acting just fine. This product has been a lifesaver! I did make the mistake of adding Denitrate directly to the baskets in my filter and some of the pieces were so light weight they were sucked up through the filter and into the aquarium, almost destroying the propeller. So I had to take the filter apart and place all the Denitrate in a media bag. However other than that, this product has performed better than expected and highly recommended.

I had a spike in ammonia in my salt tank so I bought this product to contr it, ammonia level went up. I did a complete water change and tested the ammonia but it was still high. Once I took this out of my filtration system ammonia level dropped to 0 in 24 hours. I love their products, this is the first time using this one and not crazy about it

I used this in combination with Prodibio Bio Digest bacteria on two tanks, one with about 10 ppm nitrate and one with around 30. I used one ampule of the bacteria in the 25 gallon tank and two ampules in the 90 gallon tank. I added some Seachem Denitrate media in each of four canister filters, so the bacteria would have a good place to grow (in one tray of each canister filter and in a dark bag in the back corners of each tank near the inflow tubes for the canisters where there is mild water flow). The dark bags contain about a liter of Denitrate each, and they are fat enough to have protected centers where anaerobic bacteria should be able to survive, while the outside and the high flow canisters favor aerobic bacteria. In two and a half weeks, the nitrate readings on both tanks are down to zero. Astonishing. I have kept goldfish for decades and have always had problems with nitrates. I have tried all sorts of products, and this combination is the first that has worked.

Perfecto, es lo que se anunciaba
