Excessive light or nutrients stimulate an unsightly and potentially dangerous algae bloom in aquariums, which can affect oxygen and pH levels, making water highly alkaline and thus unsuitable for fish. Green Away clumps the individual suspended particles together so that they become trapped in the filter or sink to the bottom. It does not remove filamentous algae.
