Guys I need your feed back. I have started adding SPS to my tank and I had polyp extension but now I don't and I am trying to firgure out why. 1 of my tunzes stopped working and I am working on a replacement but I still have plenty of flow. I run GFO and GAC. Tonite I tested and my parameters are

MG 1400
KH/ALK 10.2
CA 450
No3 per Salifert test kit is between 2-5
ph 7.6 per Milwaukee

I run a CA RX and I am thinking my ph is down due to C02. I know this isn't an accurate measurment but my p03 was undectecable on the salifert test kit. I was going to order the BRS phosphate meter. I have an full unit aPex that I haven't had a chance to setup.

Just want to make sure corals don't RTN or STN on me. Also my tank is med stocked with fish. Could it be my PH or N03? Where would you go from here?

Do you have any swings in PH, ALK,CA ?
You should get another PO3 test kit to ensure what your ppm on them are
Ph are you testing it manually & what type of test kit is it?

Just a couple of more things :)
 
Usually when things in my tank look bad I think of all the possible changes I have made in the last few weeks. Did any contaminates get into the system, like soapy hands...did you have any large swings like alk? Have you been dosing carbon or bio pellets? Something is irritating your corals and your gonna have to think about things that happend. You could wait it out a few days sometime sps just close up for a day or two.
 
Guys I will answer you tonite. I just checked back on my thread and I appreciate the replies and I will update this thread this evening...
