Hey all, I have been reading up a lot on zoas and with one of my colony of reverse space monsters doing the umbrella thing, am looking for ways to help it recover. It has been like this for almost 2 weeks now. There are no reaction to the polyps when it was touched (typical of umbrella effect). Other colonies are doing fine except for this particular one. I have moved it from a lower position to a higher one, as i was thinking that its not getting enough of the lighting. All parameters are on point. Im puzzled as to why. Been having it for 3 months and it just happened. Nothing changed, the lights, water params has been stable. I have read that hydrogen peroxide helps. I am looking at getting a cheaper one, at 6% concentration to try out, but does it really help and if so, whats the best way to go about it?
