A good, reliable phosphate test kit should be accessible to any serious reefer. We have found the Milwaukee MI412 Phosphate checker to be one of the most reliable test kits to measure phosphates. Excess amounts of phosphates (PO4) can actually inhibit coral growth and coloration. The most notable addition of phosphates added in a reef tank will be from the food you feed, and their is media out there to remove phosphates from the water in the tank like GFO. When running any type of phosphate removal media you should have a test kit to know that it is actually working and when to change out the media.
