I have had water issues with green water for 6 months. Water change after water change. Put this unit in after a half change and by the end of 4 days it was crystal clear in a 55 gallon tank. Nothing else worked tried chemical after chemical nothing. I would highly recommend this if you are having green water issues. Fish are happy and healthy. Way better than any chemical.

It took about 5 days before I noticed a difference. Did a water change and the algae bloom has been gone since. Tried getting rid of my algae bloom for months before I tried this. I also tried algae fix which I don’t recommend because even when dosed correctly it still kills fish. Save your money and buy one of these.

This product did exactly what it said. It took about 5 days but it was the only thing that got rid of the blooming algae. Did a 80% water change and nothing. Took everything out decorations and still nothing. This worked left is day one, right is day two
