Funny enough the recession is only on the top of the coral, not on the underside. I already have 2 mp10s in my 20g so sneaking in more flow is going to be difficult. I do have a flame hawkfish that sits and sleeps on the sps all day, do you suspect the fish might be causing unneeded stress to the colonies? ThanksThat is usually from point source lighting not getting there anymore or sometimes from debris that has settled for a bit before being blown off. With the reflected T5s, probably not that. As corals grow, colonies are a lot different than frags and mini colonies, so sometimes you need some different flow... not just more, but effective, which is hard to deal with since each tank is different. I see no AEFW bites on there, but they usually are on the bases and undersides if there is any and not on the top.
