few weeeks ago i went on vacation & left my tank in the care of my family, they first added water from the downstairs softie tank into the sps tank instead of ro water from the bucket clearly labled RO water ( i was in a hurry & didn't have time to dump the dirty water) this caused the skimmer to go completely nuts & skim out 10 gallons of water, which the ato then replaced with all fresh water, & then they let the sump run dry so for a week my poor sps tank sat at a specific gravity of about 1.012. amazingly in a pile of dead coral the squamosa clam and an acro nobilis frag looked as if nothing had ever happened.
