## Long description

Tetra NitrateMinus liquid 250 ml is a concentrated aquarium treatment designed to lower nitrate concentrations without altering essential water parameters.

The product is supplied as a 250 ml bottle suitable for repeated treatments according to aquarium volume and recommended dosage.
Advantages

Suitable for
Community freshwater aquariums with plants and ornamental fish
Aquaria experiencing recurrent algal growth due to elevated nitrate
Maintenance intervals between partial water changes to control nitrate buildup
When it may not be suitable
