API REEF MASTER TEST KIT measures the most vital reef aquarium levels such as calcium, carbonate hardness (KH), phosphate, and nitrate. Proper balance is critical to the general health of reef residents. Excess phosphate, which originates from fish waste, uneaten food, and other decomposing organic matter, as well as tap water, can create algal blooms and impede hard coral formation. Fish illness and algal blooms can be caused by high nitrate levels in fish excrement and organic substances. The API REEF MASTER TEST KIT includes four distinct tests that are calibrated to assess these levels in reef aquariums. Fill the test tubes with test drops, then compare the findings to the color card. Then, if action is necessary, follow the advice on the card.
