i think dave(morgurnda?) had a similar problem with his tank...and he checked strontium? just a thought.

 

 

At one point, most of my SPS went from growing like weeds to growing slowly or not at all. Colonies stopped growing, then started receding, and ultimately a few even died. My Ca and alkalinity were good, I could not find signs of parasites like red bugs, changed lights and flow several times. . Tried more carbon to reduce the possibility of chemical warfare.

 

Then, in desperation, I tested strontium. The kit is an absolute PITA, but it showed very low levels, so I started dosing, little by little. Well, it worked. Over several weeks, all the SPS started growing quickly again.

 

I was too embarrassed to take a before shot, but the growing tips on this birdsnest were almost nonexistent, and you can still see the coralline on the parts that had died. Now you can see plenty of new growth, and it has increased visibly even in the week or so since this photo was taken.

 

 

here it is... dont know if this is your problem but maybe it should be checked
