Ok guys quick update so i don't just leave yall hanging wondering what ever happened in the end...
so checked with the params in my LFS's Saltwater and my levels pretty much matched up with theirs other than my Alk was low. i moved the acan onto the frag rack where access from crabs is limited and did not see improvements the first day. The second day was no different than the first, so i thought maybe a feeding would help to perk it up again. That night i placed a MicroFauna LPS pellet on its mouth and after 30minutes i saw VERY little feeding response, like maybe just a small inflation but no feeder tentacles or opening of the mouth. After 30minutes of no signs of eating i turned the flow back on which swept away the food. Next day after the failed feeding attempt the Acan showed some normal looking signs of inflation. Second day after Failed feeding attempt acan is back to puffy looking self and having constant feeder tentacles out. Dont know what really did it whether it was the move or correction of low Alk levels, but everything is back to normal...
Thanks for all the input, advice and thoughts on the matter, i hope everyone elese's acans do well.
