Polyps that were in maybe dual 175 SE Mh and then placed mid to high under 400 watt DE MH, will cause possible burning or a delayed expansion.
i dont have anything close to this on my biocube 29. it has the stock lighting(2 36w PC's) and sometimes when i move them up near/onto my frag rack the skin turns red and they do not open. they normally shirnk and whither away but i found if i put them back down low and spray them with my seasquirt a few times away the red tissue will fall off and resume normal skin tone. then a few days-week later they will be open but need to color up. why is this happening??? my lights arent even strong at all.... so i now only put them down low. also what does iodine do for zoanthids and palythoas?
