Tetra Nitrate Minus 250ml

Nitrate is a natural end product of healthy biological filtration, and may also be contained in tap water. NitrateMinus uses natural biological processes to reduce and control nitrate. It is simply added to the water on a weekly basis at a dosage of 2.5ml per 10 litres. As this product uses natural processes it can take up to month to notice any reduction in nitrate levels and several months to achieve low levels. A substrate must be present for this product to be effective.
In our experience is it possible to achieve levels below 10ppm, in even heavily stocked situations. It completely safe in both fresh water and marine aquariums, even those with delicate species.
250ml treats 1000 litres
