It offers superior accuracy compared to chemical test kits, features a large LCD for easy reading, one-button operation for simplicity, and an auto shut-off function to conserve battery life. Ideal for maintaining optimal coral health by preventing phosphate-induced algae growth and supporting coral calcification. ## Description The HI774 Ultra Low Range Phosphate Checker HC (Handheld Colorimeter) is a cost-effective way to measure phosphate in marine systems, including reef tanks. 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. Phosphates are one of the many forms of phosphorus compounds found in marine waters. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp stony. In addition, high phosphate levels can cause nuisance algae growth in your reef tank. This can become problematic because algae often outcompetes sessile organisms for light, nutrients, and space, jeopardizing long term coral health in your reef. ## Features - More accurate than chemical test kits, less expensive than professional testing - Single button operation for ease of use - Large LCD screen for readability - Auto shut-off to extend battery life ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07ZG5P7XV | | ASIN | B07ZG5P7XV | | Batteries | 1 AAA batteries required.
