I have read and heard from many more experienced reefers that in a new tank, an algae bloom, especially, but not limited to, diatom algae, is normal. The general advice is also that new tank owners need to just maintain their tanks and be patient. I also know that red slime is not really algae, it's cyanobacteria. It is getting pretty bad in my approximately 3 month old 32 gal biocube. The tank houses 1 ocellaris clownfish, 1 purple firefish, 1 Banggai cardinal, 3 blue leg hermit crabs, 1 nassarius snail, and just over the past week, a small/medium sized green bubble tip anenome. All animals are thriving, and the fish get fed once a day, and I try to be conservative. I have fed the anenome 3x in his first week in the tank, but this cyano problem started before he arrived. Lights are on for 7 hours & I do weekly 10% water changes, using Red Sea Coral Pro salt. I change the filter floss 2x/week. There is about 30# of live rock, & chemi-pure carbon that gets changed about every three weeks. The one filtration component I haven't purchased yet is a protein skimmer (which is planned), and currently I have only one wave pump for circulation ( a second is also planned). Last water test: T - 78 F, Salinity - 1.025, Nitrate - 2.0, Phosphate 0.025. (I haven't detected ammonia or nitrite in so long, I didn't test for them before yesterday's water change.) I think a skimmer will be help but I am wondering if I should be taking more drastic measures to get the cyano growth (assuming that's what it is) under control, like carbon dosing. In these pictures, some of the hairs growing from the cyano would almost reach the surface if I hadn't brushed them off the rock a week ago. It really is starting to cover the rock and the sand. I can brush it off the rock but it comes right back. Any advice would be greatly appreciated. -- OK, I have tried to upload photos of the mess and for some reason, they are not uploading, which has not been a problem in the past. All I can say for now is that pretty much any surface exposed to light has what I believe to be cyano on it. I will try to upload photos in another post.
