When used as directed, CrystalClear® pHGuard™ will stabilize pond water pH and maintain buffering capacity as safe levels between 80-240 ppm. CrystalClear® pHGuard™ will help prevent wide pH swings which are typical from morning to night. CrystalClear® pHGuard™ makes pond water safe for fish and plants and helps keep water balanced 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.
