Flow looks fine to me.
Here's my take on the flow issue. These anemones are from shallow water so they are typically accustomed to higher flow and higher light than some other species might be.
There is definitely a question of minimum flow, but the way I think of it is, what's more important is that surface agitation for O2/CO2 exchange and then adequate mixing/dispersal throughout the whole water column. Secondly, there needs to be enough flow so that any slime or detritus cannot build up on the tissue - it needs to be blown off. This will work to prevent an opportunistic bacterial infection. Beyond that, observing the anemone and using our intuitions to make further adjustments is likely good enough. I don't think it's truly necessary to have a hot tub type tornado-in-a-tank effect going on, even if there may be specimens out there that are in those conditions it doesn't mean they all have to be. Just try to use your common sense, imagine the part of the reef they come from, and see what you can arrange for.
Ie., so there should be plenty of flow, but we don't have to stress too hard over whether its called for or not to be constantly giving it more. As long as the requirements are met about O2 and slime, just watch the anemone and see how it reacts. Slowly ramping it up is probably better too, over a sudden significant change that shocks it.
Is it eating yet?
It is so great to see these anemones BTW.
Good luck with them all to everyone who was lucky enough to score one!!
