Please help with Dino ID

[chinw76]

Hi, I have dino on my sand bed and my gyres. I would just like an id of them please. I have done a second slide on my scope and added 2 drops of dino and 1 drop of 3% peroxide and they stopped moving. Nitrate is 5ppm and Phosphate at .038. I have been dosing both daily and also dosing silica to try to create diatoms to out compete them. These are on my sand bed, gryres, not on corals, rocks have turned a little brown. The images are are close as I can get on the scope.

using rodi water?

Yes. I have had this tank for 2.5 years. I just need to have them identified so I can find a solution to solve the issue. My Ro makes 100 gallons a day, has a booster pump, I added a time delay relay that will purge water for 4 mins before water goes though 6 stages of DI resin. It goes through 2 stages of cation resin, then 2 anion resin, then 2 mix beds resin.

I don't think there is enough detail to get an ID.

Check out this guide and see if you can maybe get an idea https://www.reef2reef.com/threads/dinoflagellate-identification-guide.671466/
