Thomas Cornish –
I’ve used Phosphree in my 500-liter reef tank for three months. The water clarity has improved significantly. No fish stress or changes in behavior. Easy to add and maintain.
Trevor Buckland –
The 250ml size worked well for my 1000-liter tank. Phosphate levels dropped noticeably after two weeks. No residue or odor. Good value for the performance.

Switched from a metal-based filter media to Phosphree. Water stays crystal clear and my corals look healthier. No metal ions detected in water tests.
