    Hi all. I'm sure this topic has come up before but please bear with me. I'd like some advice as which test kits are more accurate for detecting phosphates? From what I can tell there are two types of pho spam to check for I.e. "Salifert's kit and most other kits only measure inorganic phosphate. The Merck/Deltec kit and colorimeters measure orthophosphate which is what gets metabolized".

    I use the salifert kit. I am concerned however about my phosphate levels specifically for sps corals. From what I understand you need to test for orthophosphate for sps corals. Am I right? Colorimeters are very expensive so I'd like to know how you guys with sps corals test for orthophosphates? Is there a cheaper option?
