This is my 55 gallon tank. It was just used for fish but I am now trying to sell it. I noticed once I brought it outside that the glass was extremely cloudy. I tried to scrub the glass with a non abrasive sponge and some white distilled vinegar but that didn’t work. I’m afraid I have no idea how to remove this If anyone has had any experience with this or has any idea how to remove the cloudiness, I would greatly appreciate any input
