Ok, I have not read everything in the stickies, but I have looked.... I am getting a second hand tank. The whole thing appears to have been shut off and not cleaned - there is a salty residue over everything. I'm sure taking the ole Windex out and cleaning it is probably something that will kill anything that I plan to put in this thing, but how do you go about cleaning an aquarium? I figured I would just fill it with water, and submerge everything for a few days to just get things dissolving, but any recommendations on what I should to to prep it for the actual day I get to put something in it?
