So Today I was gonna change my water and clean out the accessories in my tank. I wasnt sure if I was allowed tho so I left it for now. But my sunken ship is getting some crazy algea growth on the sails so I wanted to take it out and clean it real good but need to use soap or something since the sails are fabric. Is there any chemical or soap that I can use to clean them and same with the glass. I have a lot of calcium on the glass cuz of hard water... Whats good to use on that. Thanks in advance for the help!
