Tetra Nitrate Minus can be used for the long-term reduction and control of nitrate, leading to better water quality and less algae.
Nitrate is a natural end product of healthy biological filtration, and may also be contained in tap water. High levels can encourage excessive algal growth, which can make the aquarium look unsightly. NitrateMinus reduce and controls nitrate, for improved water quality and better algae control.

Simply add to aquarium once a week - no need for resins that have to be replaced or recharged

Add 2.5ml of NitrateMinus per 10 litres of aquarium water, on a weekly basis. Dose rate can be doubled for additional nitrate control. Depending on the starting concentration of nitrate in the aquarium, it can take a few weeks to reach the desired level. Once achieved, levels will remain low.
