## Overview

Seachem De Nitrate Remover is a 1-litre biological filtration media engineered to reduce nitrates, nitrites, ammonia, and organic waste in aquariums. Its high-porosity granules provide an ideal environment for anaerobic bacteria, crucial for nitrate reduction, while requiring a controlled water flow (up to 200L/h) to function optimally. Unlike sulfur-based alternatives, it eliminates the risk of hydrogen sulfide production, ensuring safe and stable water conditions. Backed by thousands of positive reviews, it’s a must-have for aquarists seeking effective, low-maintenance nitrate control.

## Description

Review: This product works but only if you get it right. - 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.
Review: Nitrate remover that works! - 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

## Questions & Answers

**Q: Could this product cause my previously clear water to go slightly white cloudy?**
A: I purchased this a bit hasty, i only use seachem as the products seem to work. I used this for about a month and noticed hardly a difference. Then i notice seachem Matrix, after using the Matrix Nitite has stayed at 0 and has got my nitrate down by 5-10ppm.

**Q: is this okay for a freshwater temperate tank?**
A: According to the bottle it works for marine and freshwater aquariums.

**Q: I have an internal filter with a spray bar. Can I put this in a mesh bag and tie it to the spray bar (so it gets water flowing through it)?**
A: Yes you can, however this will dampen down the water turbulence..

**Q: Can I use this product with plants or will it take away the nitrate they need to grow?**
A: yes you can use it with plants . the plants should get every thing they need from the fertiliser
