CeeGee: If you look at the dates, it has been almost 2 months since the dying coral incident. As far as what I did to save things, I just maintained high water quality at consistant levels. One of the things that I'm doing on a weekly basis is water changes. When I had softie tanks, I never did water changes, but with the SPS/LPS, I guess it helps out. I still never figured out what caused the RTN to occur, but everything that survived is doing fine and growing.
Some of the upgrades that I'm doing is:
Larger sump/refuge - going from 40gal to 120gal (for 225g total)
Zeovit (no flaming please!)
Larger skimmer
Calcium reactor
14k Phoenix bulbs
Tunze turbelle's (w/ controller)
That's all I can think of for the moment.
