CrystalClear PondShock ball is powered by billions of all-natural, live bacteria and enzymes to rapidly break down ammonia, nitrites, and organic waste. It is designed to give your pond an extra boost during times of change, such as spring start-up, after using an algaecide, after a storm, or after a fish spawns. One CrystalClear PondShock ball cleans, clears, and balances ponds up to 2,500 gallons for four weeks.

PondShock also helps jump-start your biological filters in the spring to reduce ammonia spikes when new fish are added to the pond. A great alternative to chemicals and does wonders to balance your pond ecosystem.
