De Nitrate Remover, 1 Litre

I've always had problems with nitrates in my tank. It's not overly huge and seems to build quickly regardless of regular maintenance etc. My water change routine was getting pretty drastic in order to keep on top of them to the tune of over 60٪ once a week. Not ideal! Having checked all possible causes and still getting nowhere I decided that building a nitrate reactor was the way to go. It's been a week since my last water change and since the nitrate reactor went into operation using this product. Based on past experiences, a week down the line, my nitrates should be well over 40ppm by now. They're not. A test this morning reveals the nitrates are somewhere between 10 and 20ppm. The reactor is still maturing but already its had a significant effect on the water. This product works, no two ways about it. It is very picky however. It requires a specific flow of water in order for it to do its job. One should bear in mind when purchasing that this product doesn't remove nitrates on its own. It merely serves as a home for the bacteria that do, and if one doesn't create the ideal condition for that bacteria to grow then all you'll have is a reactor full of small porous stones. If the flow is too high or too low, it won't work. If it gets too cold or hot, it won't work. To set up mine I overdosed the reactor with Seachem Stability both before it was installed and continued adding 10ml daily afterwards into the water near the reactor intake for seven days. I created a water flow through the reactor of approximately 128L/h which is around 33GPH (US) above Seachem's recommended minimum flow. I'm still a beginner in the world of fish keeping. But with proper research I got this product to do its job on my first attempt. I must say that if it doesn't work for you, then you've done something wrong.

Been struggling to get nitrates in my aquarium down. Numerous water changes and other products tried no luck. Popped a few of these in the filter and after 2 days the test strip went from bright pink to light pink and still dropping but not too quickly to shock my fishies!! Excellent product! Update: still use these in my filter and Nitrates staying at bay! No more pink strips

Seems to be working.

Excellent product. Reduced nitrates overnight

Great quality, nice price.

Why did you choose this product over others?: Saved my cycle in my tanks!

Been in my filter now for about 2 months and nothing as really happened regarding Nitrate levels going down... Hence the 3 stars.

Not a quick fix for nitrates after 4 days still the same

Fast delivery. My tank’s nitrates went down as expected.

Superb clear water

One of my larger salt tanks had a couple mishaps with dosing and over feeding which caused nutrient spikes and a large presence of ammonia, phos and nitrates. The tank is 90 and the sump 30 gallons just above the water line. With all the rock and sand and boi media, call it 70 gallons of water. I bought two of the 16oz bottles and it was the perfect amount to fill between the sat baffles of the sump heading into the return bay. Those pebbles turned from pearl white to a dingey light grey in just a couple weeks which means it’s almost time to swap it out. The sponge filters in the baffles cause a decent amount of phos and nitrogen which is being forced through the media beneath it (similar to the way a reactor works) and this product does what it’s advertised to do. 8 hours later the nute levels were stable and have remained so for 6 addditonal weeks now. Very happy customer. Ordering the bucket now. Thanks for an amazing line of producer, seachem!

Between the Prime and this, my new tank stabilised in a matter of days after elevated water parameters across the board.
