Phosphate Ultra Low Range PPM Colorimeter HI774 Hanna Checker - Marine Water

The HI774 Phosphate ULR checker provides an accurate way to measure phosphate from 0.00 to 0.90 ppm in a few easy steps.

Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly small polyp stony (SPS) corals. In addition, high phosphate levels can contribute to nuisance algae growth in your reef tank. Algae often outcompetes sessile organisms for light, nutrients, and space, jeopardizing long term coral health in your reef. Testing for phosphates is standard practice for saltwater aquariums and provides valuable insight into your reef tank’s water chemistry to help ensure long-term coral health.
