Thanks to both of you guys.
Being as the heat ain't gonna hurt a thing, I'm going to close up the lids and let the tank warm naturally. It'll be like soup in no time. I do need to go get a decent thermometer though.
I'm going to start bringing down the salinity tomorrow. I can only pull it down ten gallons at a time because my RO unit is so slow.
I'm going to drop a bit, so far as salinity goes, but I'm not going to drop it too low. I've been dropping slowly over the last year, coming down from 1.025 to 1.020. (I typo'd that last message, Carlos.)
I'd like to hang around .018 or .019.
Since I've lowered my salinity, my coralline has flourished as well as my critters, bugs, corals, and fish. This outbreak was caused by temperature spikes. I need to cut off the heat run behind the tank. That'll be a pain, so it'll wait till summer.
Thanks again, guys!!!
