Dinos?

So I have a new tank, 220g + sump and I'm 99% sure I'm in the middle of dealing with Dinos, from what I can tell possibly Amphidinium and Coolia. Tank has been running for almost 4 months, and has some livestock - blue tang, purple tang, some chromis and some pajama cardinals. A few zoas, a duncan and a hammer. Basic CUC with some snails/hermits/cleaner shrimp. Livestock wise, everything is doing well and I've had no issues. I dosed ammonia to start the cycle, and then most of the fish went in early on. I haven't added anything in 3 weeks since what I originally thought was a diatom bloom started.

Amidst the new tank setup, I got married and was less attentive than I should have been. I added some chaeto to the tank and was running the refugium light for 18 hours - I'm pretty sure I bottomed out on PO4 or NO3 at some point - I'm still having issues keeping it stable. Refugium light is down to 5 hours a day. I started overfeeding, and my PO4 is at .02, NO3 is at 2.7 as of tonight. Both are down slightly from a week ago. I don't have UV set up.

I have some NYOS Phosphate and Nitrate coming to have a failsafe, but figured I'd start out asking for help confirming an ID and any suggestions on what direction to go in.

We were all super excited to see everything under the microscope so cut me some slack on the commentary ;)
