What else is in the tank? Sudden bleaching would make me think temperature, but you could rule that out if there are other inhabitants that aren't affected. Slowly add more RO water to your tank to bring your sg back down to 1.025-6. Are you usign a refractometer or hydrometer? If you use a hydrometer, it likely is not accurate. Take it to LFS for them to compare to refractometer or calibrate it yourself: http://reefkeeping.com/issues/2004-06/rhf/index.php

test with refractometer, with water change I was able to get it back to 1.026.
temp is a pretty constant 79.5 - 80.1 Magnesium is 1400 only other thing I've done out of the ordinary was to switch bottled RO water, noticed that the new water I'm using lists Demineralized water and ozone as ingredients, where as the water I was using before said it was 'natural spring water filtered by Reverse Osmosis'. Both have a TDS of 4ppm but wonder what effect, if any, the addition of ozone would have. Colin
