Phosphate Test Strips
Managing phosphate levels is the most natural way to AVOID ALGAE blooms
Phosphate - Phosphate occurs naturally in the environment. It is an essential nutrient required for algae growth. Since phosphates come from a variety of sources, it is recommended that you test your phosphate levels when you open/close your pond and weekly throughout the season. Phosphate levels may be lowered through partial water changes or the use of water treatments.
