This listing is an offer for 1 x Envii Pond Klear Xtra and 1 x Envii Sludge Klear.

In winter keeping pond water clear is not the problem, but sludge build up is. Envii Pond Klear Xtra 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 Xtra

Envii Pond Klear Xtra works well in both filtered and unfiltered ponds. Although the clearing process may take slightly longer in unfiltered ponds due to the bacteria having to do all the work. Typically results are seen within the first couple of weeks with a further three to four weeks required to completely clear the pond.

Envii Pond Klear Xtra treats up to 60,000 litres.

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.

6 Envii Sludge Klear tablets treat up to 30,000 litres.

Don’t use pond vacuums as they can remove all of the beneficial bacteria in your pond and can lead to green water and algae.
