Please help! my Button Polyps are freakin out

[fishkiller]

My button polyps for some reason are not coming out like they use to. They stay kinda half shut, like a grail-shape. I tested and everything is ideal. I havn't testedfor calcium or phosphates yet.
Can somebody PLEASE tell me what I need to do!! Thanx!

Start by testing for Calcium and Phosphates.

ok my friend had the same problem. its all about lighting. first try putting them closer up to the light, if the problem persists then get new lights maybe. my friend got 50/50s for his tank and now they open up. i also have a 50/50 in my tank and i was even able to revive my dads button polyps that were half dead!
