Owen McLean –
I’ve used AlgaeFix for three months now and noticed a significant reduction in green algae and red slime. My coral and shrimp are thriving, and the water stays clearer. No side effects on my invertebrates. Great product for reef tanks.
Peter Jones –
It works well for controlling brown algae in my marine tank. I added it once a week and saw less algae buildup. My anemones look healthier. A little pricey but effective.

It helps a bit with algae, but I still need to clean the tank regularly. Not a complete solution, but useful as part of a maintenance routine.
