Hanna HI 774 Checker HC Colorimeter - Phosphate Ultra Low Range

Hanna Checker Marine Ultra Low Range Phosphate Colormeter HI774 is a valuable tool that simplifies the process of monitoring Phosphate in your marine system. High levels of phosphates can prevent coral growth, calcification, and skeletal formation. Additionally high phosphate levels can cause unwanted algae to grow in your tank. If algae begins to grow in excess, it can be detrimental to the health of your coral long term, as algae outcompetes other organisms for space, nutrients, light and even oxygen. Without those requirements, coral will be in jeopardy. This handheld checker is an easy, accurate and affordable way to measurement phosphate from 0.00 to 0.90ppm. The HI774 efficiently and accurately measures phosphate levels so you can keep them well within a safe range for your inhabitants. The compact design fits perfectly in your hand, or pocket, features an easy-to-read LCD screen, and an auto shut-off feature, so the battery doesn't drain unnecessarily.
