Hello. It's been a while since I have logged into Monster. I sold my 72 Gallon BowFront and have given all my African Cichlids to my brother in law. Anyways....Just the other day my Father in law got me this tank for free from a friend of his, and as you can see I got quite a mess. I am aware when the tank is full of water, you really do not see most of the water stains. I have used a razor blade, Vinegar, and even CLR then cleaned the tank with salt water, then dried it. As you can see the stains are still there! How do I remove these stains, is it possible?
