Po4 level

Sorry, but there's no such number. Keeping it too low (below .03 mg/l) will have a negative impact on coral's photobiology potentially causing bleaching and death. Upwelling will expose corals to levels as high as .2 mg/l so somewhere between those numbers is probably what's best. (Research shows higher levels increase growth rates but also can make skeletons more brittle.) Here's some links if you want to look into the roles of organic and inorganic (PO4) phosphorus in reef systems:
