Featuring one-button operation, a large LCD screen, and auto shut-off for battery efficiency, it offers professional-level testing at a fraction of the cost of lab services.

## 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.

Review: Great product. - Great product and easy to use.
Review: Most accurate phosphate checker on the market - While I’ve used other test kits for a while, it wasn’t always easy to determine the exact right color that the readings showed, and the range of results were sometimes a bit too broad and not specific enough in certain ranges. With the Hanna kit, it’s just as easy to test (despite the slightly finicky packets that you have to add the contents of into the small test vial), and the results are always an exact reading that leaves no room for questioning or wondering what the results might be like the color chart test kits can do. It’s a bit pricy compared to other kits, but it’s well worth the price if accuracy, consistency, and ease of use are important to you. Highly recommend the Hanna Phosphate checker!
