Help me with ID and what to do now.

Hello, I have a one year old 75 gallon mixed LPS SPS reef. Started with 75 percent dry rock, 25 percent Kpaquatics rock. I have had slime with bubbles on and off all year. Was mainly on sand now on rocks mostly. I borrowed a cheap microscope and have some pics and video to try for identification.

Dinoflagellate Ostreopsis

Exactly what Dan_P said if I remember correctly that type of Dino go into water column and can be taken out with UV.

I have a cheap in tank uv I just turned on. I was dosing nopox to keep nitrates and phosphates low, aiming for nuder 10 and .10 but it sounds like I was fueling dinos! Should I dose hydrogen peroxide at night? Microbacter daytime?

Agree Ostreo dino which often occurs when there are biological deficiencies and the dino has consumed both po4 and no3 and are multiplying and in turn many dose no3 and po4 to bring numbers up not realizing they are feeding these flagellates even more. No light is first key followed by the addition of bacteria to overcome the bad bacteria allowing them to thrive
Prepare by starting by blowing this stuff loose with a turkey baster and siphon up loose particles. Turn lights off (at least white and run blue at 10% IF you have light dependant corals such as SPS) for 5 days and at night dose 1ml of 3% hydrogen peroxide per 10 gallons for all 5 nights which works as an oxidizer. If you dont have light dependent coral- turn all lights off. During the day dose 1ml of liquid bacteria (such as micro bacter 7 or XLM) per 10 gallons. Clean filters daily and DO NOT FEED AMINO OR ADD NOPOX which is food for dinos, however you can feed coral, food which will help no3 and po4 to increase. If increasing nutrients, try to keep no3 to about 5 until you are done battling these cells.
Doing a daily siphoning will help greatly But . . . . . Siphoning will reduce nutrients , so siphon the water into/through a filter sock and save the water and return it back to tank. Obviously clean the filter sock each time.
You can feed fish as normal and if doing blackout, ambient light in room will work for them

What said. I can tell you what I did but I had LCA. Tried everything and when I saw change is when I put three bags of pods from reef cleaners in my tank.
