SPS Phosphate level

I've always aimed for about 0.01ppm, but always having had efficient filtration means a lot of food needs to go in...

I am happy with .04 to .06, Hanna Checker is not perfect but the corals don't seem to mind. I ran BP for a while at about twice the dosage and stripped everything from the water, almost lost everything. Now I just dose a little VSV and run HCGFO when needed. The tank is too new to feed heavy but it won't be long before I get the bio-load up there and begin feeding heavy again.
