Jave you considered dosing hydrogen peroxide? It will kill algae and not hurt aptasia from what I have seen.
I would set up some sort of rack with multiple glass or egg crate to increase the surface area substantially.
I would also experiment with the type and amounts of food your feeding, possibly cutting back.

I would just skip the UV. The whole idea of using a colony from a single descendent is to achieve a nearly isogenenic culture or strain. UV works by mutating DNA. So if any polyps run through the UV, even if not killed, you'll accelerate mutations. I say this speaking as a Drosophila geneticist.
