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 out competes sessile organisms for light, nutrients, and space, jeopardizing long term coral health in your reef. 

  • Take your portable handheld colorimeter anywhere. 
  • Simple, one-button design makes getting your results easy. 
  • Improve your technology and upgrade from your standard test kit.

simple and quick

This is my first Hanna checker and i'll never go back. The salifert test i was using before worked but i hated reading the color chart. once you figure out how to get the powder out of the package and mixed it's quick and easy. Read the instructions, I didn't realize you have to hold the button and a countdown starts before giving you the number.
