I bought an aquarium second hand and I'm having issues with hard water stains being etched into the glass. I have had fish tanks all my life and I've never come across something I couldn't clean, until now! This is driving me bananas. I've tried vinegar, baking soda, Barkeepers abrasive powder and foam spray and I've even let it sit outside with fresh water in it for a week and it hasn't helped at all!!! Is there any advice you can give me?
Some people have tried fine auto sandpaper, 5000 grain or something. I have tried some fine sandpaper that we had kicking around and that didn't do anything either. A scraper doesn't work... Is it hooped???
It doesn't look horrible when it's filled, but it's a drag, because it is (or was) a beautiful 50g bowfront aquarium....
