Since upgrading my lighting, the unsightly faint white haze throughout the inside of my 20 gallon is untolerable. It isn't a thick calcium or lime build up, rather extremely thin and patchy, as it dried on b/c of water spots. It feels like scratching a chalkboard. I've already tried Pythons Rydant 2 aquarium cleaner, which is advertised to remove Ca/lime build up; it hasn't on the glass, but only the thick stuff on the rim.
Are there any good metohds to turn my glass back to crystal clear?
