Algae are one of the most annoying problems in our hobby. They can completely overrun a tank, causing plants to die. In extreme cases, algae growth might even cause the entire collapse of an ecosystem.
Preventing algae is one of the most important skills when setting up a tank, and understanding what causes algae bloom is a very important aspect of maintaining a healthy ecosystem.
Algae are not always bad, and in small quantities, there’s nothing wrong with them. However, they are often an indicator of other problems in your tank.
Observing your tank and identifying the type of algae is crucial to combat the problem, which is what this page helps you do.
