The Causes of Algae Buildup

Algae buildup is generally caused by too much light, too much organic matter, or too many certain nutrients in the water, such as phosphate and nitrate. If you have too much light, it will cause algae to grow faster than normal. If you have too much organic matter, it will break down and release nutrients into the water, which can also cause algae to grow. Lastly, if you have too much of certain nutrients (like phosphate and nitrate), it can make it easier for algae to take over.
