Ok so I just got a 34G Solana from a friend of mine. The problem with the tank is that he let water sit in it for about 9 months. No light, no circulation, it just sat there. Most of it evaporated out but there was still about 6" in the bottom. I can scrape the front and the sides no problem. I can get the bottom too. The problem I have is with the back. There was a sponge and a bunch of bio balls back there that he never took out. The back is pretty nasty. I obviously can't get my hands in there very good to clean it. A friend of mine suggested that I put vinegar in there and let it sit. Will that kill all of the nastiness in the back?
