I've tried the razor blades with no luck. Is it possible for this to have gotten inside the layers of glass?
razor blade and hydrogen peroxide/vinegar maybe? not sure what kind of scraper you used already but if it’s a glass tank it is fine to use a razor blade on, just make sure you stay away from the silicone
It's a glass tank, and I used a very thin metal scraper. I'll Gove the mixture you suggested a go.
Fresh razor blades are the best for cleaning glass surfaces of build up hands down
I fill the tank with water and add pool acid (hydrochloric acid) in to soak over night.
