I drip my kalk so it's not like it gets bombarded with CA.
Here is what has happened with my experiment...
I moved one of the acros to the frag tank yesterday afternoon. Last night I noticed a few polyps extended not many but a few. I left he acro in the tank all day. I thought I saw a few peeking out, still had to really look to see any. I just checked tonight and again I see a few. The few I see tonight seem to be out a tiny bit more. I can actually see one blowing a bit. I was going to move it back to the main tank tonight but a pony is sleeping on it. I also noticed the pony slept on it last night as well. I didn't notice the ponies on it at all during the day at the several times I checked on it. I have also been watching a few of the fish a little closer. I have seen the flame angel, coral beauty and yellow clown goby all appear to be nipping at different coral once in a while. Nothing consistant. I do have several SPS and find it hard to believe all of them are closed just because of nippers...
So what do do now?

Any one of these 3 fish could caused closed polyps during the day - these fish are variable, some nip, some don't. But you have these fish and closed polyps. Odds are high that is the problem. The hard part is we like these fish, so we don't want to believe they are the problem.
In my old stonies tank I put in a yellow clown goby. The next day all sps polyps were closed. I removed him a month later, and several days after that all polyps were open.
In my current stonies tank, I added a flameback angel. The same day, all sps polyps closed up. I haven't been successful removing him yet, but I will. I am lucky, I have another tank (softies) that I can move him to.

I just do not understand how one fish can cause 20 some frags to stay closed, I can watch my clown goby and the polyps around him close but the rest of the coral is open and if he moves corals the same thing, it is only the area he is in

"They are a peaceful fish that makes a wonderful addition to a reef aquarium containing colonies of polyp corals, as they enjoy swimming and hiding amongst the polyps. However, they may nip at the polyps of SPS corals. "
I had many of the same thoughts as you, but tried everything i finallly just took mine out on saturday and am already noticing better extension.... I still see the flame nipping from time to time, but can't catch him.

IME, polyp extensions has most to do with phosphates. I got my phosphates down to very near 0, and continually test my phosphates with a good phosphate test kit(D&D). Since then my polyp extensino has been great.
I also believe that flow has a good deal to do with polyp extension. I have a lot of flow in my tank which I think helps a lot.

I agree that many conditions can cause low polyp extension. But when you have fish in the tank that can cause this, it can be a lot simpler to remove the fish than to figure out which of the other conditions could be causing the polyp retraction. It is surprising to me that people wonder what the reason can be when they have fish that are known to cause reduced PE for at least some tanks.

reduced PE and no PE are really two different things, for a few fish to cause 100% of the corals to not open just does not seem right to me

Take a piece of one inch tubing start a siphon and use the water suction to catch the goby. Once he is in a 30 gallon trash can you can net him.
It took me less than three minutes to catch mine that way.
If you have a seperate tank it is a quick variable that can be eliminated from the puzzle.

Glad it worked for you too....
I'm in this one with you.... hopefully we can help each other figure this out.
I tested my PO4 last night and it was undetectable on the Aquarium Pharm test kit.
I still don't have the 1/4 inch polyp extention my A. Millipora had a month ago when i brought it home, but i can atleast see the polyps since removing the goby..
Wish i could catch the F. Angel.
Does anyone have an opinion about leather corals potentially releasing chemicals that could hender polyp extension?
