Seachem Denitrate 1 Liter

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

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!!

Great product, it’s lowering my nitrate levels in my marine aquarium

WITH HUGE TANKS AND HUGE CICHLIDS AND LOTS OF FILTER SYSTEMS......AND BREEDING PAIRS...the nitrites and nitrates wouldnt stay balanced.....read reviews...not to much on the one here....i was totally shocked how cheap the 1 litre is and even more shocked how quick this worked....i always buy with skepticism.....2/19/24...easy to use...make this your stand by..will buy again

Clean's water

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

Absolutely amazing! I'm veryyyyy new to fish keeping I have a 65 gal african cichlid tank and I've had two mass die offs and just could not figure out what I was doing wrong and why I couldn't keep my water healthy. I've been using this about 4 months now and I've not lost a single fish in the time. Ammonia nitrate and nitrites have all been perfect the hole time.

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.
