Seachem De Nitrate Remover, 1 Litre

Great quality, nice price.

Takes a while to process in the water

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.

Very good thank you

Completely removed my NO3 from 20 to 0 after 3 days. Full recommend for everyone

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

Just as it says on the label, fast shipping and good quality.
