reef aquariums are one of my favorite things to observe. I have started up my own reef aquarium resently, it isn't going so well right now, but it has been getting better in the last few weeks, and am still having problems with nuisance algaes. I have some colony polyps and did have some star polyps, but they all died. My colony polyps were about to die also but I put them into a smaller tank and they started to open up again. some kind of a flew must of went threw my aquarium or something, but I cleaned up my tank and erverything seems to be all right now.   IT WOULD BE GREAT IF YOU COULD GIVE ME SOME TIPS.
