Hi Guys
I got this zoa colony a few weeks ago, they all opened up first few days then mostly stayed closed, all params are ok except KH 13.7 dkh, Nitrate 25ppm, phosphate was 1ppm tho just tested 3 after adding 12gram bag of rowaphos 3days ago ! confused.....
Anyway params aside, I've noticed these black things on some of the closed polyps, what are they any ideas?
Cheers Paul
