Reef Zlements Z-Phosfate Liquid Phosphate Remover 1000ml
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 directly into the skimmer pump or skimmer neck.
PhosFate can be dosed using a dosing pump, however please dose carefully and according to the below recommendations:
| Phosphate levels per day/100l | Recommended dosage |
|---|---|
| 0.04 – 0.25 ppm | 0.1 – 1.0ml |
| 0.26 – 1.00 ppm | 1.1 – 2.5ml |
| 1.10 – 5.0+ ppm | 2.5 – 5+ ml |
Do not overdose. Although dosing is effective, excessive use may reduce filtration efficiency.

I’ve used PhosFate for three months now and my phosphate levels have dropped consistently. The skimmer handles the phosphate removal efficiently without any issues. Easy to dose directly into the skimmer neck. Works well with my reef tank setup.

Good product, especially for maintaining low phosphate. I used it with my skimmer and noticed a clear improvement in water quality. Dosing is simple and the liquid is stable. Slight improvement in clarity after a few weeks.

This remover has made a big difference in my tank’s stability. Phosphate levels were above 1.0 ppm before, now they’re under 0.3. I dose it directly into the skimmer and it integrates smoothly without affecting water chemistry.
