I just got a baby (3-4 month old) gold tegu. When i got it i had to some rearranging with the cages and i had to break out the old 29gal tank that used to house saltwater fish to house my crested's. The problem is that there is a what seems to be a calcium deposit film on the inside of the tank. I have tried EVERYTHING under the blue moon to get it off. Vinegar, bleach, soap and water, dish soap, scraping it with a razor blade and scraping it with a paint scraper. The only thing I havent tried is CLR (Calcium Lime Rust remover) but I was advised against this and it probably wouldnt work anyway. Anyway i would like to know what the heck i can do because the tank looks horrible but i dont have another $40 to spend on a 29gal cuz i just spent a lot setting up the tegu's cage >.< Any help is much appreciated.
