I am certainly seeing ostreopsis. Hopefully that is all as it is relatively easy to kill off. If @taricha gives a like to my post, then I guessed correctly and you can do this in order of importance:
1) Get a UV running. One watt per 3 gallons running into and out of the display not the sump. Seriously. Run at as slow as the manufacturer allows (maybe 300 gph)
2) Obtain nitrate and phosphate dosing solutions. Thousands of options. Brightwell makes premixed to stay simple but expensive. Dose to achieve at least 10 and .1 for nitrates and phosphates. Red Sea test kits for nitrates; Hanna ULR Phosphates
3) Clamp or suction cup onto your glass a bunch of filter floss into high flow and high light areas of the tank. Rinse every evening. You can export A LOT of dinos this way.
4) Run a bunch of GAC (granular activated carbon) as ostreos generate a fair amount of toxins that kill inverts and coral.
5) Shut down anything that removes nutrient from the water. I keep skimmer running but very dry. Socks are ok.
6) Baste your corals/rock/anything to get the dinos into the water to be killed by UV or otherwise exported.
Good luck. You have lots of good company and you came to the right place.
