Things You'll Need
- Bucket
- Clean sponges
Instructions
Fill a bucket with hot water. Make the water as hot as you can. Dip a new sponge in the hot water and start cleaning the tank. Never use a sponge or cloth that has been used for another purpose, since any leftover contaminants could harm your fish. Avoid the use of window cleaners or soapy water.
Scrub the inside of the tank with the sponge and the hot water. You might have to scrub extra hard at the top of the tank, along the rim, to remove any calcium deposits or dried on salt.
Use a razor blade to remove any stubborn calcium or mineral deposits. If the tank has been used with very hard water, you might see a line of white around the rim of the tank. Remove as much of that staining as you can with just the hot water and the sponge.
Fill the tank with water, and allow it to sit for at least a day or two. This will ensure that the tank is watertight before you start using it and stocking it with fish.
