gsp coral has not opened After

gsp coral has not opened since i put a hob
skimmer 100 gallon in my 40 gallon breeder
could this be the problem ? It was nice and open before, skimmer has been running for 4 days and water is crystal clear it pull out alot of waste already

No water change
No new light
Salinity 1.025
Everything was fine until I introduced the protein skimmer and I don’t want to take it off because I really like what is doing

New tank, nitrates and phosphates may have gone to zero with the new filter and that might make your star polyps angry and hungry. They thrive in dirtier water. Shut the new pump off. Dump a bit of the skimmate back into the tank and see if the gsp comes around.

Wouldn't it be smarter to Test the water parameters since that's a good place to start on all diagnostics?

My assumption filled diagnosis was based upon information given in the post, but of course you are correct that testing would supply more specific information. I also presumed the poster does not test nutrients since only salinity was posted?

Is GSP the only thing in this new tank? Any fish? Do you feed the tank? GSP are like cockroaches. Hard to kill. You're going to need good test kits on this adventure. Might as well start now.

From experience, GSP can close down when something changes (like any other coral) but will come back 100% of the time. Just make sure you stabilize your parameters.
