Transform murky, green pond water into a healthy, clearer aquatic environment with Pond Klear. This natural treatment uses millions of beneficial bacteria to break down the organic debris and nutrients that feed algae and cloudiness, restoring clarity and balance.

It’s a gentle, chemical-free solution that’s safe for fish, plants, pets and wildlife - helping reduce the likelihood of future green water while encouraging a thriving pond ecosystem.

How to use: Test your pond’s pH, adjust if needed, then add the correct dose diluted in pond water; repeat weekly until clarity is restored (up to 6–8 weeks for very murky ponds).

Some pond keepers report dramatic improvements and long-term water clarity with consistent use, while others note that very stubborn green water can take patience and multiple treatments.
