How do I clean water stains?

Bar Keeper’s Friend is $2 at WalMart. It’s impressive how quick and easy it cleans up a tank. The King of DIY’s video shows him cleaning a tank that’s been sitting around empty and was never cleaned after it was torn down. Effortless. He’s got at least two videos using it.

distilled white vinegar and elbow grease... its safe for your fish. Will still have to clean either every week or every two weeks...
