I will have to try and slowly add a few cuc members back as the other algae grows to battle it. But I will wait for more of the dinos to go away first.
I haven't picked up a UV sterilizer yet. I need to get my hands on a microscope first so I can see what kind of dinos I have. Apparently there is one type that doesn't get into the water column and UV sterilizers aren't useful for it. Plus I was hoping to get some hanna test kits on black friday. Will have to see.

R2R is also where I got my information and how I decided on treatment. it's great that you're going follow up on the microscope which is really the most important part.
as you mentioned a UV will be very effective on water column species like amphidinium and you may not even need any further treatment. this is obviously what you're hoping for as some of the people I followed had horrible issues for months and once they added the UV were able to clear their tank in the first few nights.
Unfortunately, UV will have little to no effect at all on prorocentrum which stay in the substrate and where you're better off to establish an environment that encourages algae growth that is too nutrient rich for dinos. this can (and did in the case of my tank) take months where you have a really poor looking tank that is overrun with algae if you don't have something that eats a lot of it.
Also, I don't know if I mentioned it earlier but you can cut a little of the toxicity your inverts take on by running a little activated carbon in the meantime.
good luck!
