My Personal Phosphate Supplement Made From KH2PO4 Mono Potassium Phosphate and RO/DI Water.
Keeping the proper phosphate levels in your reef tank is vital to coral growth and coloration. For many of us who sit at zero or near zero nitrates need to supplement when feeding and fish stock isn't enough. I personally test and dose phosphates twice per week keeping my levels between 0.08 - 0.15ppm.
