Re: Minor Bleaching... Lack of some supplements might be it.
Good calcium, alkalinity, magnesium would be my first level. Second level would be strontium, molybdenum and iodine.
I test for all but strontium and molyb. which I just follow instructions for dosing when not testing. May get a test kit for those eventually.
I'd probably get new lights too.
Hope that helps.

EDIT - Sometimes they will bleach regardless of supplements. RTN is a disease and water temperature and flow also come into play. |
