Aquarium Advice Apprentice
I just recently noticed that a few of my mushroom corals look really bad in the later part of the day for two days straight.. a couple of my other Kenya trees and green star polyp look a little rough too, I recently have had an outbreak of cyanobacteria in my refugium (lack of flow I think?) and in one part of my tank, I have Just removed 50 % of my bio balls (I think the bio ball removal may have stirred up a cyano bloom?) any Ideas of what may be happening I have noticed cyano has eaten the polyp that was in the refugium could this be the cause? and further more how can I control this cyanobacteria outbreak this week I have done 1X40 % h2o change and doing another 40% tonight, kind of stumped thanks for any advice..
