PO4 of .02 is too low for corals you keep IMO.

What level are you suggesting is better?

I successfully grow acropora corals with PO4 between .04-.08. In my experience LPS and soft corals will be happy with higher PO4, up to .2 in some cases even higher.

OK, thanks. One of the reasons I usually suggest levels more like 0.03 ppm phosphate is to somewhat limit the growth of problem algae. If you can keep it adequately controlled, higher levels are likely fine (IMO).
