Please help me identify these Dinos!

Hello Friends,

I have been fighting an outbreak in my established tank that I cannot seem to beat. I've narrowed it down to Dinos by purchasing a microscope and doing some investigation. What I find is that these are mostly 'coffee bean' shaped and I believe they are either Amphidinium or Prorocentrum. I was thinking more of Prorocentrum, but if you enlarge, you can see the 'beak' I believe is tell tale with Amphidinium.

I'm a novice here, so if anyone has any comments they will be greatly appreciated. Also any help with getting them under control would also help.

Thanks
