Truthfully, I would think more flow would be beneficial instead of causing deflation. Try a water change...they always seem to help things that are hurting. What are you feeding? It may be(not saying it is) if you are feeding silversides that you should switch to mysis. Feed with selcon and garlic dosed mysis shrimp every day to every other day. I've heard problems with siversides bones getting caught in the anem and choking/tearing the insides. That fear keeps me only feeding deshelled(unless the chitonous shell is thin enough to be eaten, like mysis, krill, copes, etc) inverts to stay away from anything sharp, hard, and pointy going inside of my fleshy, boneless structured anems. I overfeed my anems and have never once seen them expell waste, which mean the food I feed is being fully utilized by the anems.
I know people love silversides and swear by them, but is this just because a store tells you that's what they eat or have you done any trials with other things such as squid, clams, scallops, oysters, mysis, or other such products? Since I stopped silversides and started invert meals, my clowns have grown significantly, colored up much nicer, and the anems can't get enough of it...they are sticky, bubbly(sometimes), and very healthy. I know I got a little off topic, especially since I don't know what you feed, but if you do feed silversides, maybe try a switchover.
