I have a colt that's generally in the 7-8" range. Lately, it's been opening (full brown polyps out), but deflating (about 2-3" tall instead of 7", stalk looks week, branches bent and limp).

Nothing significant has changed in the tank - same location, same light, same flow. Bulbs are PC (4x65W), about 7 months old. Added some ordinary Turbo snails and hermits, just to replenish what had disappeared over time.

Everything else in the tank except a GSP cluster looks fine - that cluster also isn't opening, which is unusual. All inverts, fish, and other soft corals are fine.

My hunch is that there's some outside pollution - my wife generally burns a lot of candles in that room, any chance that's irritating the system? Anyone have any other ideas?

Do your basic water tests just to make sure things are alright as far as that goes, esp. pH and KH. Ifyou suspect candles, sprays, etc, best thing to do is a decent size water change (at least 25%); you might want to put some carbon or a polyfilter in the system to help remove any potential toxins too.

I'd do a water change as said above, it cant hurt, thats for sure, put some fresh carbon in as well
