Our safe and effective nitrate remover

Envii Nitrate Klear is a safe and effective nitrate remover for reducing potentially harmful nitrate levels in your pond or aquarium. Reducing nitrate levels helps prevent problems such as green water and algae growth as they use the nitrates as a food source.

Bacteria that have been obtained from natural water sources are used in our nitrate remover. Therefore, they replicate processes in your pond or aquarium that naturally occur. They compliment the nitrogen cycle, which is a natural process that takes place in all ponds. Targeting nitrates, they gradually break them down and digest them to reduce nitrate levels.

You can use Envii Nitrate Klear as a one-off nitrate remover to decrease nitrate levels, or alternatively, as an ongoing treatment to keep nitrate levels low and pond water healthy.
