So I got some green star polyps about 10 days and its been great out and flowing around now I come home from work and half of them are closed up and the other half look like this the only thing I did different is remove a sponge that I put in my filter and added some chaeto cause my nitrates were going up am I killing it? I tested the water and everything is practically the same the only thing different is calcium is down to 420
