Well ultimately it should starve any exisiting algae, that uses phosphates, out of existence. I don't know what happens when that algae "melts away" (or whatever it does) into the water column and adds to nutrients, I assume its just skimmed out.
I take it you're using phosban in the reactor? I bought one about a month ago and used rowaphos in it for 3-4 days. I had 4 SPS frags RTN completely and two more had tissue recession from the bottom up when I took the reactor offline, once I did that the tissue stopped receeding immediately.
Right now I have carbon running in the reactor and it works awesome
I may try the rowaphos again but bring the reactor online slowly to acclimate the corals to less phosphates or whatever change they didn't like in the water. Either that or I'll be trying phosban soon.
