So the orange stuff seems to be going away on its own. However, parameters are not improving... I'm thinking that I'm going to break down this tank soon. Maybe this weekend. Planning on selling all my fish stuff that I won't use in my next tank to help fund it. For now, I only have time to maintain one tank so the next build will be my only one. I'm still trying to decided on the Mr Aqua rimless 11.5 gallon or the 12 long. Pretty sure I'm going to go with the 11.4, it's close to the same dimensions as a standard 10 gallon, and will be a lot cheaper to build. 18" fixture rather than a 36" and I'll probably still be able to use my aquaclear filter. BUT a 36" long tank sounds nice.... It's just so short! I'm torn... What do you guys think???
