Ya, I tried the tang method as well.. lasted 3 days and died. First 2 days, model citizen eating the hair algae like a pig and swimming great, day 3 dead on the sand. Ugh.
Anyway.. this morning actually is a good one in my tank. I hooked up my new "ghetto" sump to my tank on Thursday. 35G rubbermaid bin, 50lbs of good live rock, good skimmer (which is still doing great, I can't even compare it to my remora, it is on a different level), and new filters on my RO/DI unit, along with knowing the water is now back to "normal" levels in my area. So I did a large waterchange when I hooked up the new sump, everything got really mad at me immediately after, every coral that had any life starting sliming bad as soon as I turned the return pump on, which I thought was going to be the last straw that put all my corals out of their misery.. but 36 hours later and for the first time in a month my corals seem to be wanting to make a comeback. There are actually polyps out on my red planet, something I haven't seen in a week, so there may actually be hope of saving some of my corals. I still have to cut them up to cut out the really dead parts, but I think I may be able to save parts of about 1/2 of them if they are now on a path to recovery and not declining anymore.
