Polyps receed during daytime?

Thanks Codfather. comforting to know that others have similar settings to mine - 250's & depth of tank....

However, brings me back to "why" the polyps retract?

Sorry - Type-o in original note Calcium is actually 430. I've also been doing quite a few water changes lately & use Canadian springs bottled water (I couldn't find a good supplier for Perrier ;-)

What about the amount of time Corals take to adjust to their new environment?? Different for each one?

hmm are you using any zeovit systems? Phosban reactors?

In some cases, I have had frags that took weeks to finely colour up and get good PE. Try placing it in several locations, might not like the spot it's in. Flow might have some factors as well, I have noticed better polyp extension after I bumped my flow to around 10000 gph, and my tank dimensions are 45" x 30" x 24" high.

what fish do you have?

I have a Potter's angel so some of the SPS keep retracted during lights on, but fully extend at night - others are extended no matter what time.

I agree with the flow portion. I had a piece that was getting lots of flow polyps were out all of the time. After a position shift, where it was a bit sheltered, has caused it to have very little.
