Hey guys and gals. this is my first time posting here. My aunt just gave me her 50 gallon glass tank. The tank has been sitting dry for a while. It has green algea all over the walls and hard water stain all over it. Im just looking for advice on cleaning it and getting it looking good again before i start to cycle it. I have used a razor blade and got most of the algea off the walls but still has some on the caulking on the inside corners that i did not attempt to get off with the razor blade. so is there any good product or home remody that would help to get all the algea out of the tank and the waterstains off. thanks for any help in advance
