    I bought this 96gallon corner tank from someone used the other day. He had it as salt water. The top 2 inches of the glass are cloudy and it's not coming off with my vinegar solution. Any ideas?

    Bleach and water would probably get it. Just make sure and rinse it well afterwards

    To add on to what @Jswin said, when you fill it up with water, add a larger than normal dose (3-5x) of Prime that will get rid of any CHLORINE from the bleach. Then after a day I would drain it, inspect the glass to see if its up to your expectations, repeat the bleach treatment if necessary, otherwise fill up, condition and cycle as you normally would

    With a glass tank, you can use a razor blade scraper.

    I tried the blade, but there's really nothing to scrape it feels smooth.

    I bought a used tank (freshwater) that had a really bad film on it as well. I sprayed it with straight vinegar, let it soak for a few minutes then scraped it with a blade. It felt smooth as well but I did get most of it off. I had to do it a few times and it never came as clear as new but it was a big improvement.

    Have you tried using a Mr. Clean Magic Eraser? Don't need anyone to flame me ,but quite a few people have used a stronger acid, like CLR . if you use a strong acid be really sure to neutralize with a lot of baking soda and rinse, and rinse , rinse, and rinse some more.

    I would suggest vinegar method that's what I had on my tank when I converted it to fresh. May take a few tries but that looks like hard water build up. Vinegar should eat through it. Just rinse really really well !

    You can get it off the best you can but once you set it up you're fresh water will eat away at it and soon it will be gone. My tank had the same thing.
