If your tank is properly stocked, balanced, and maintained, you should not need this product regularly. It is for situations where you have had to be a little slack in water changes, etc, and need to catch up with the algae in the tank. Always do a water change first, and remove what algae you can, prior to use.
If you are finding that algae grows back quickly you need to find out why, and eliminate the issue.
