Sick zoos what do I do?

it could be the peppermint picking at it which he'll be gone tonight anyway.

That would most likely be you cause. Most shrimp will pick at a necrosing coral and in many cases increase the damage that has already occured.

The Pipe has some flow, not real strong, actually the PH flows over it not directly on it. It also gets some gentle flow from the fuge outlet. The stuff doesn't seem to be coming over it as fast today, but I did something different, the Selcon I didn't add, I have been using it all week and today I haven't been, do you think it could have been the Selcon?

It is possible if the concentration of vitamin C has gotten too high. Try just dosing every other day instead and see if it continues to show improvement.

Cheers
