1.09 is WAY to high so I'm going to guess you ment 1.009... I don't know, but then again I've never used extended hyposalinity. Lorna would be best to ask for that one.
I don't think the anemones are going to survive either way... the picture you posted of them looked pretty bleached out in my opinion. Putting them in direct sunlight would probably kill what's left of the algae that lives inside them (Zooxanthella). Plus keeping them in a bowl has it's own set of problems... I honestly don't have a suggestion here... Hmmm... Do you maybe have anyone in the area (with VERY good lights) that could take them?
So far as a UV, yes on your tank a 9 watt would do just fine. Before I say what flow rate though, could you let me know what brand it is (or is available to you)? Or even a link if it's online? A lot of UV's advertise a flow rate that is too fast to really be effective. Plus there are a lot made for pond's that are only intended for clearing green water. They can be useful though, just have to *really* dial down the flow rate so the pathogens get hit by UVC light for longer.
So far as taking anything back... if the store won't, you're just going to have to try and get them healthy so you can sell them to someone who does have a proper tank .
