ostreobium are green algae that live within the skeleton of living corals, Under nutrient poor conditions it causes no harm, but sufficient availability of nitrate or po4 it will grow faster than usual and will encroach on the coral and cause the live tissue to recede. The only way to control is to limit the nitrate on po4 levels

But what if NO3 and PO4 are already testing negligible to zero? I have the same problem. I tried running zeo to get rid of NO3 and PO4 .. didn't help. I run NO3 destroyer. NO3 is zero. It doesn't help. Acros drop dead after a few weeks. No obvious parasites. I wonder at times if it could be some kind of bacterial problem that once it gains a foothold there's just nothing you can do to eradicate it, because it's odd to me that out of 3 distinct reef tanks that I run, the same results happen in each of them. I used to be able to keep SPS - I can't anymore. Everytime I buy "test frags" or "test colonies" I get reminded within a few weeks that I am just wasting my money.
FWIW here are my numbers of the last tank I am trying SPS in. Ca 420, Alk 8, NO3 2.0, PO4 0.0, Mg 1390, SG 1.025. Source water is RO/DI. Water turnover is roughly 50x. SPS can be one of the most frustrating and futile endeavours once it gets to the point.
