Reef Zlements Phosphate Liquid Phosphate Remover
PhosFate is an extremely efficient liquid PO4 remover that works by binding to phosphate and allowing mechanical filtration like skimmers and filter rollers to remove the phosphate from the aquarium. We recommend PhosFate to be dosed into the weir before a roller mat filter, or directly into the skimmer pump or skimmer neck. PhosFate can be dosed using a dosing pump.
Available in 2 sizes: 500ml & 1000ml

I’ve used PhosFate for three months in my reef tank. The phosphate levels dropped significantly after a week of regular dosing. I added it to the skimmer neck and noticed no visible deposits. My corals look healthier and the water clarity improved.

Works well when dosed before the roller filter. I followed the recommended dosage and saw a steady decrease in phosphate. No flocculant appeared, which is a relief. Only used it once a week.

Great product for maintaining stable phosphate levels. I mix it with my skimmer pump flow and it integrates smoothly. My tank has been stable for over two months with no issues.
