Hello from Miami ! So, like everything else I do in life, I decided to go over board. I got this 80x37x36 beast in my living room. Empty, for now. I'm just staring at it thinking what did I get myself into. Anyways, seemingly not a bad craigslist purchase. Only the glass so far (550.00). I slapped together some 4x6's and some ply and I have a lower stand. So, bow, I'm trying to clean this thing. And there's a milky cloudy film (inside and outside on the glass)in some areas , of course the front and middle, that is impossible to get off. I tried CLR, vinegar, wetsanding, razor blades and short of shooting it with a .45, I cannot for the life of me get it off. Any suggestions... Planning FOWLR aggressive. No soft corals or anything. So I guess , lighting and filtration ideas would be cool too. Thanks !
