I have a 40 gallon tank which I bought used and I didn't realize that there are some phale white marks on the front glass till i brought it home. It's not a scratch it just looks like there is something dripped on the inside of the tank and discolored the glass. I tried so many different ways to clean it but I had no luck So I thought to reach out to WAMAS.
Does anyone here know how to restore tanks? and can do this for me? I am in MD but I don't mind making a drive to drop the tank off and stuff. I was going to add pictures but it's kind of hard to see on a picture.
