With 2 reagent sets enabling up to 50 tests, it helps aquarists maintain optimal water chemistry to prevent algae growth and support coral health. Backed by a 1-year warranty and trusted by professionals, this kit is essential for anyone serious about reef tank management. ## Description The HI774 Ultra Low Range Phosphate Checker is an affordable tool to measure phosphate levels in marine systems, including reef tanks. High phosphate levels can hinder calcification, skeletal growth, and development of many coral species, especially SPS or small-polyp stony corals. Moreover, elevated phosphate levels can stimulate unwanted algae growth in reef tanks, potentially outcompeting sessile organisms for light, nutrients, and space, thus threatening long-term coral health. Regular phosphate testing, a common practice in saltwater aquariums, offers valuable insights into your reef tank's water chemistry, helping to maintain long-term coral health.
