Envii Pond Klear Xtra (1L)

Unlike other treatments that can clear pond water quickly, the biggest advantage of Envii Pond Klear Xtra is that it tackles the source of the problem, keeping pond water clear. Other treatments sink particles to the bottom of the pond that over time, float back up into the water column. Envii Pond Klear Xtra breaks down these particles, preventing them rising back up in the pond and impairing water clarity.

Envii Sludge Klear (6 x tablets)

Envii Sludge Klear is a pond sludge remover that contains millions of beneficial bacteria. Their job is to target pond sludge, break it up and get it to the water column. From there, your filters can catch it and it can be physically washed away. Envii Sludge Klear will work in ponds that don’t have filters but can take longer to work as we’re relying on bacteria alone. The bacteria in Envii Sludge Klear are capable of working 4°C to remove sludge and improve water clarity.

Envii Nitrate Klear (6 x tablets)

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.
