Water Quality
Do you know what is happening in your aquarium, what it needs, and what it doesn't? You should, and testing your aquarium water tells you what is going on. It allows you to make any necessary corrections to fix a problem, such as with pH, unwanted nitrate and phosphate, and when to add beneficial calcium and other trace elements that are essential to reef systems.
