hello fellow reefers! i have a problem. I got new bulbs for my tank (ushios), and a new skimmer(g3), other than that no changes have occured in my tank for a very long time. 2 days ago the halemida was fine now its got this on it... is this normal? looks to me like a fungus... but im no expert, all advice welcome, i plan to get some more this weekend. will this stuff affect my whole system i have 2 mangroves, Chaetomorpha and Codium Taylori everythig else seems to be ok.
