Our Envii Pond Klear Xtra is a natural pond treatment that uses beneficial bacteria to clear pond water. Containing three times more bacteria than our flagship product Envii Pond Klear, it effectively clears both green and murky water by binding together the particles and sinking them to the bottom of the pond.

Keeping Pond Water Clear

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.

Works with Filtered & Unfiltered Ponds

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.
