Used Antiphos FE in my saltwater tank for two months. Algae growth decreased significantly. The product is easy to add and works well without harming my corals or fish. I noticed a clear improvement in water clarity.
Dominic Campbell –
Good product for reducing phosphate. It took a few weeks to see results, but after three months, my tank had much less algae. I plan to use it regularly as part of my maintenance routine.

My reef tank had persistent green algae. After adding Antiphos FE, the algae stopped growing and the water became clearer. No negative effects on my shrimp or anemones. Highly recommended.
