Thanks, but I should have been a little more clear in my question.
The Eclipse 12 is a seamless plastic tank. I got it used, and its about 5 years old.
Over time the plastic itself developed a haze to it that does not come clean.
I believe it could be from light exposure because when I removed the frame around the lip of the tank and the substrate the plastic that was covered by both is still crystal clear.
I'm just wondering if there is something that will help.remove this haze;
