CrystalClear pHGuard - pH Buffer

CrystalClear pHGuard, when used as directed, will stabilize pond water pH and maintain buffering capacity at safe levels (between 80-240 ppm). pHGuard will help prevent wide pH swings, which are typical from morning to night.

pHGuard makes pond water safe for fish and plants and helps keep water quality problems from arising in the hot summer months. Keeping a properly buffered system is essential for the completion of the nitrification process which allows harmful ammonia to be converted to nitrite and then to nitrate.

pHGuard is safe for use with fish, plants, birds or domestic animals that drink from the pond.
