    Glass problems.

    When I removed the plastic background from my ten foot tank, I realized that moisture had become trapped between the outside of the glass and the backing.

    It's left a kind of white film on the glass, which is now very obvious with the new backing in place. I've tried to remove it with some windex, a scouring pad, and finally a razor blade scraper. Nothing.

    Is it now etched into the glass? I can't believe it such a big problem. I mean Melbourne water is very soft, with very little mineral content, and it is just water, nothing else.

    Anyone got any clues? Short of painting the back of the tank, I'm stumped.

    Hi Merrilyn,
    what you are reffering to is waterstain on the glass. It is caused not from mineral in your water but from the mineral in your glass. there is no way of getting rid of it if it is bad. Cerium oxide works on light water stain.

    Darn.

    I thought that might be the case.

    I'l try rubbing some vaseline into it and see if that disguises it, otherwise it's going to be a case of heavy planting to hide it

    Thanks for the info Rex.

    Vinegar, should do the job Red
    Just plain old white vinegar and leave it for 30 min "do not be shy with the amount of vinegar either SLAP IT ON"
    If that does not work .
    A little stronger stuff might be required EG: Phosphoric acid solution

    I'll plaster some paper towel soaked in vinegar on the back of the tank, and see if that makes a difference. Thanks guys.

    I have used CLR to remove badly scaled glass in showers. I loaded it on and still had to use a soft scourer. It took a few goes but it did come up like new. So if the vinegar doesn't work it's another suggestion

    Great. I'll get some CLR if the vinegar doesn't do the trick. Thanks. :P
