Hey Maselah,
I assume your polyps are moveable? I take mine out each week and put them in a small cup with tank water. I then put in a small chunk of frozen brine formulav in with them and gently stirr. After about 5 -10 minutes, the polyps start coming out and I gently stir the water and it flows formula particles into them. I the let it, then stir, then sit then stir ect... Then put them back in the tank and they come out happy and raging!
