Help Identifying Type of Dinos

[revak29]

Hi everyone, I’m looking for some help identifying the Dino’s that are in the pictures attached. At least I believe they are Dino’s. I have seen similar pictures that allude them to being either Coolio or amphidinium but they don’t seem to match exactly. Can anyone help me in IDing these and the best course of action to eradicate? They are mostly on the sand but have seen them attach/bother my Duncan coral causing it to contract and I’m starting to see tissue receding. Thank you!

Do you have microscope photos that aren't red?

I didn’t take any pictures without the red filter, the microscope I have is a cheaper one and the red filter allowed for the best view. The other colors made it hard to see them, including the white/clear filter.

Thank you so much! Is there a best practices method to beating them?

Currently, I’m running a black out with dosing of MB7 and Dr. Tim’s Waste Away and was going to try to get my nitrates and phosphates up as right now they are at .03 for phosphates and 0.0 for nitrates.

My tank is the fluval evo 13.5g tank with a ai blade grow light, a media basket from Etsy that holds filter floss, polishing pad, activated carbon and gem ceramic media. Therefore, I’m a little limited in what I can add to the tank.
