Jerry, I just want to emphasize to you and others that vinegar, muratic acid, and other lime removers must never be used on the inside of a set up tank. If used on the outside of a tank with fish, be very careful not to get any in the water. Like the others say, it is to be used on empty tanks. Mike Wise "Jerry F.
