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. Why Choose CrystalClear PondShock? Rapid clarity: Targets ammonia, nitrites, and organic waste to clear cloudy water fast. Biofilter support: Helps seed and replenish beneficial bacteria after clean-outs or media changes. Easy use: Toss the ball in and let it disperse with the included activating gel. All-pond compatible: Safe for koi, goldfish, aquatic plants, and backyard wildlife. Flexible dosing: Use monthly or any time water quality needs a natural boost. Water Treatment Temperature Guide Start: Use when water is consistently above 10°C (50°F). Best range: Performance is strongest in typical spring through fall temperatures. Cold periods: Avoid use in near-freezing conditions when bacterial activity slows. Dosing Instructions Standard dose: 1 ball treats up to 2,500 gal for about 4 weeks. Larger ponds: Use additional balls to match total volume. Placement: Drop into a high-flow zone like a skimmer basket or near the pump intake. After algaecide: Wait 3 days before dosing. Do not divide: Use the whole ball; do not cut or split. Heavy load: Dose a bit sooner if fish load is high or water turns murky again. 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.
