All my SPS other than Acroporas are retracting.

I recently helped a fellow reefer tear down his tank and as a reward for my help, he gave me a lot of SPS colonies.

All the new colonies, regardless of species, show great polyp extension and feeding response.

Now the strange thing is that all my own SPS colonies have completely retracted and remained so for over 3 days. Stylophora, pocillipora, montipora, enchinopora, etc., etc. are all showing the same response.
Oddly as it seems, none of my acroporas are freaking out whatsoever.

All my parameters are great and nutrients are undetectable. I changed carbon and gfo just to be sure, but it doesn't look like it helped.
The tank is 14 months old and the new colonies was less than a 5% biomass increase to the system. Fish and other inverts seem happy and healthy.

I haven't experienced anything like this before.


Do You have any advice or experience with something like this?

I have found, that when asking for help, people here generally don't respond to things like "all my parameters are great".


That doesn't mean anything, really.

Thank you. I'd be happy to elaborate.
