Well I screwed up big time last night...... I was gonna run a little ro/di water into the sump while I plumbed in the chiller I bought off Mike. Long story short I left it on all night and even with my sump designed to hold a lot of extra water in case of power failure I flooded my dining room and living room...... The worst part is all the runover and extra water dropped my salinity to 1.012. Corals are closed up looking pitiful but fish seem allright so far. Except I haven't seen any of my mandarins all day. Shopvac'ed till I was worn out and got dryers blowing on the carpet right now so the house will survive and hopefully the creatures will too. I have been bringing the salinity back up by added small doses of salt to the sump (after draining the excess fill water). once salinity is back up I will start testing for everything else(parameters). Wish me luck!
