This listing is an offer for 1 x Envii Pond Klear and 1 x Envii Sludge Klear – green pond water cure and sludge remover. In winter the problem is not green water, but sludge build up.

Envii Pond Klear clumps any organics held in the water and sinks them to the bottom of the pond for Envii Sludge Klear to digest. Only Envii Pond products work at temperatures as low as 4°C due to its patented bacterial strains.

Envii Pond Klear

Envii Pond Klear contains millions of beneficial bacteria that target the microscopic algae and nutrients in the pond. They clump them together and sink them to the bottom of the pond where they can be removed via the pump and filter or digested by the bacteria.

Envii Sludge Klear

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.
