One one of my tanks, the glass appears to have a "haze" to it. It seems like it is some sort of film. I think it may be algae or salt deposit. A few weeks back the tank was drained cleaned out moved upstairs at my house then filled again. I used an aquarium brush thingey in attempt to remove all of this haze. I thought when i filled back with water the haze would dissapear, but hasn't really. I used a razor blad to scrape off as much as i could while tank was filled last week; I did see algae come off, and the haze got a little better but still there.
I have heard of people using some products that may help. and i also heard of using vinegar. I haven't attempted either one, mainly because I would need to remove the fish and drain the tank, etc.
Does anyone have any experience in this sort of thing? and could share some ideas?
