CrystalClear pHGuard stabilizes pond water pH and maintain buffering capacity between 80-240 ppm. Crystal Clear pHGuard will help prevent wide pH swings which are common from dawn to dusk due to fish respiration and plant photosynthesis. CrystalClear pHGuard is sold in a 2 lbs container and treats 8,000 gallons
A properly buffered system resists changes in pH due to acid rain & other external factors. Alkalinity is also essential for bacteria to complete the nitrification process, which allows ammonia to be converted into nitrite and nitrate. A drastic change in pH may cause stress or even death in ornamental fish & plants. Safe pH ranges for pond fish and plants are 6.5-8.0. It is important to remember that pH is typically lowest at dawn and highest at dusk. Therefore, it is important to test your pond at the same time each day to measure results.
Routine Application Rate
Apply pHGuard once a week and after each water change.
For Best Results
pH is typically lowest at dawn and highest at dusk so it is important to test pH at the same time of day.
