467-16736 - Tetra Pond Sludge Reducer up to 250 gal 4 blocks

Sludge Reducer blocks contain billions of beneficial bacteria and enzymes that quickly break down the unsightly waste that accumulates 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.
