GSP has not opened after 2 weeks

[DragonStone]

I bought a GSP that was completely open at the pet store. Closed when they put it in the bag and had been closed nonstop for 2 weeks. Occasionally a few little pieces come out but not fully open. What should I do? Other corals in the tank are open

Salinity is a little low. My corals like some nitrates. They used to be up in the teens, but have slowly dropped to 5-6 and steady.

how old is the tank? Corals struggle in brand new tanks. Your test kit is likely an API kit? To keep corals will need some good quality test kits, API won't do. Need to know alkalinity, calcium and phosphate and nitrate as the most important.

A pic of your tank will also help to provide more suggestions.

Corals can take hours, or days, or weeks to acclimate to a tank. So, hard to offer suggestion to you without knowing much more details about your tank.
