Are you using the low-range Phos
phorous checker that reports in ppb? If so then to convert to phos
phate first multiply by 3.066 then divide by 1000. (Nice and intuitive, no?)
But if it says ppm on the unit then you probably have the phosphate checker.
Took me a little while to realize they are two different checkers giving two different sets of results but at least you can convert the reading from one to the other with the handy dandy maths...

Sorry if I missed this info but are you running GFO? I ask because I notice you mention the zeovit products (Zeozym etc.) and FWIW, I was running zeovit on my tank with absolutely no testable reductions in PO4 over a period of well over a year. I started using gfo and that is the only thing that made a difference in my phosphate readings (and overall tank health)...
