Algal blooms are caused by excess sunlight and excess nutrients together with many other factors.

On the other hand, there are some clues that snails feed on cyanobacteria. Cyanobacteria is the cause of green-blue algal blooms. However, snails cannot completely eliminate those algal blooms on their own. In conclusion, don’t rely on snails if there is an algal bloom in your tank.
