The aquarium has hard water stains, and the glass looks really cloudy. I've read that vinegar works, but I tried that, and not much came off. I also read that some people lay the tank on its side to soak the stains, but I wondered if that would damage the tank somehow. It's a 55 gallon.
How do you rinse out a tank after you've cleaned it? I mean, I can rinse it, but I don't know that I'll be able to remove 100% of the water that ends up in the tank after rinsing. How can you be sure there is no residue left that will harm the turtle? With the ten gallon, we used to take it outside and hose it out. Obviously I can't do that every time with the 55 gallon, or with a bigger tank when we upgrade.
