When your pond turns cloudy or tests show rising ammonia and nitrites, a quick biological boost is often all it needs. This self-dissolving ball carries a heavy load of live bacteria and enzymes that get to work right away, helping your filter stabilize and your water clear without resorting to harsh chemicals.
It is especially handy after spring clean-outs, storms, or any time you add new fish. Drop it in, keep the water moving, and let the bacteria colonize your media so the system can process waste more efficiently.

PRO TIP
For faster results, clean or rinse mechanical filter pads first, then place the ball where water flows through them. The bacteria will colonize that media quickly, helping your system handle waste more efficiently right from the start.
