Need troubleshooting help

I can't keep bubble tip anemones happy and could really use some help figuring out why. Gonna be a long read because I'm gonna run down the whole setup soup to nuts:
Display is a 150g tank with 2 corner overflows. 30g sump and 40g refugium. One overflow goes into fuge (which gravity flows into sump) and one to sump. Two return pumps plus one big closed-loop feeds lockline jets all across the back/bottom of the tank behind rockwork.
Two 250w SE 20K halides under Lumenarc reflectors and two 5' T-5 actinics, bulbs changed every 6 months or so.
Korallin calcium reactor keeps calcium steady at 420 and alkalinity [dkh] at about 7.5-8 (would like that to be higher but coral health is so good I ignore that number :). pH is generally 7.9-8.3 throughout the day.
Biopellet reactor and GFO reactors keep nitrates and phosphates low. I feed oyster and phyto feast every other day and fish get fed once a day, one or two cubes. Bioload is moderate- one 4-5" gold spotted rabbitfish, one 4" mimic tang and the rest are small blennies, gobies and wrasses (mystery and potters leopard).
Corals grow like mad- there are tons in the tank, everything from soft to sps, mainly sps but lots of lps too, and everything in the tank, literally every coral, is growing well. Even a flowerpot that has doubled in size in one year.
I've have a long tentacle anemone for about 6 months, doing very well, and a tube anemone that is ok for about a year. 3 mini carpets for about 2 years now, and a rock anemone hitchhiker since I started the tank (about 4.5 years ago). Here's a short video of the tank:

I've added 3 bta's over the last 18 months and each time they look great for a couple days then move into the rocks and are never seen again. All 3 were healthy and acclimated slowly. My best guess is too much light but that just doesn't hold up when I see other people with similar setups, 400w halides, super clean water etc.
Help! Any ideas?
 
My guess would be the same as yours. Not so much "too much light" but the combination of bright light, limited time to acclimate, and then they pull into the rocks and are gone.

What lighting do you have in your fuge? You might consider putting your next bta in your fuge first (since they don't need very much light) and seeing how it does while acclimating to your water chemistry. Then assuming it is still looking good after a week, you will have eliminated many of the possible causes of demise associated with water alone. This will also allow your to try different lighting schemes to bring the anemone up to the lighting levels in your main tank - without have to mess around with your main display.
 
Thanks! That is a great idea- I will try that asap. Makes so much sense.
Refugium has T-5s over it, so not nearly as strong as main tank but not terrible either.
 
There are already three different types of anemone (I'm not counting the tube anemone) in that tank? I'm surprised that Bonsai Nut didn't raise allelopathy as a possible explanation for why the BTAs aren't doing well.

Your other nems have adjusted, but maybe it's just too much for a newly introduced nem trying to acclimate. Since you've got good light and your water quality is high enough to support your corals, that would be my vote.
 
Hadn't thought of that either. But I tried adding a BTA before I had any of the others except for the mini carpets and hitchhiker so I would be surprised if that was the cause of the problem.
 
The nice thing about working with a refugium is that it will allow him to adjust some factors (lighting) while keeping other factors the same (water chemistry, temperature, etc).

If allelopathy is an issue it will present itself in the refugium as well as the display tank. I would be surprised if this would be the case in a 220 gallon system but you never know...
 
You were right BonsaiNut. A week ago I put a bubble tip anemone in the refugium and it has been open huge since about a minute after I put it in there. It is clearly very happy- always fully inflated.
So now I will wait a while (a month?) and increase the light. I have a 60w LED that I can put over the fuge- anyone think that's a bad idea?
