Ha, no kidding Timfish. We do also keep entirely different systems and corals for the most part so it makes sense.
Kim, are your chalices fading color or is it more of a bleaching of color? Are they getting more dull and light or are they going almost completely white/clear? Chalices are very sensitive to being exposed to too much light. I agree with Timfish on the leather... they always looked ticked until boom... they are happy again.
Remind me how the transition took place? Was the first tank fully cycled prior to moving corals/fish over? Were you ghost feeding to keep the bacteria level higher in the new tank? Did you use new sand? What type of sand?
How long were things in the system before you started noticing things not looking happy? Did you keep the kessils at the same strength or increase/decrease them from your prior tank? Are your husbandry practices still the same in both tanks (i.e. water change frequency, feeding frequency)? What media or technology are you currently using? GFO, activated carbon, biopellets, skimmer, macro?
Sorry for the twenty questions but just wanted to make sure I had the whole picture. If you're ever in the area, be happy to test your water for you. Plus, it'll give me an excuse to catch up with you! If I ever venture down south, I'll hit you up and see if you're around.
