OK, so the used 90 gal tank I bought the other day is really great, but I do have a question. The glass seems a bit tinted! Kind of a very, very pale smokey tint to it. It wasnt noticable when empty, but it is now with water in it. Can this be changed? Is this just the type of glass? It actually makes the tank look kinda cool, I have an oscar and a green terror in there and a few plants and some nice big river rocks and it sort of makes it almost look as if I used black water extract in it. My other tank (65g) has a very clear glass which is what I am used to seeing, but I have never seen tank glass such as this before.
