Biological Filter Starter. PondCare BioFilter Booster is a highly concentrated solution of beneficial bacteria that start up and maintain the biological filter in water gardens and koi ponds.
Goldfish and koi continuously release harmful ammonia into the pond. Uneaten fish food and decaying algae also cause ammonia and nitrite build-up. The beneficial bacteria in BioFilter Booster quickly establish the biological filter and begin breaking down these harmful substances and improving water quality.
Regular use of BioFilter Booster helps the biological filter remain active all season long. Reduces the build-up of toxic chemicals from fish waste, uneaten food and dead algae. Will NOT harm people, pets and wildlife.
