Sludge Reducer blocks contain billions of beneficial bacteria and enzymes that quickly break down the unsightly wastes that accumulate on the bottom of ponds as a sludge layer.

Sludge Reducer blocks are also ideal when setting up a new pond and during the spring startup and fall shutdown of established ponds. The blend of bacteria and enzymes is beneficial for developing and maintaining the pond’s biological balance resulting in a cleaner and clearer pond.
