Controlling dinoflagellates with Metronidazole

I added a UV sterilizer and kept my micron filter running. Believe it or not I started adding phosphates and nitrates to get my values up out of the basement. I have read that the Dynos are a low nutrient loving organism and competition is the way to go. Since adding phosphates and nitrates I have encouraged some hair algae and coralline algae to colonize the rock work. The hair algae is a lot easier to control with grazers. I am working at getting my grazing population up and everything should be fine. I still have a tiny bit of dynos but they are not actively growing.

Thanks for the update Frogger.

That's an interesting findings. The time that dino appeared in my tank is the time when I started dosing AF Component 123 and after my tank hit 0 nitrate and 0 phosphate. I'm still struggling to raise nitrates and phosphates at this time as I continue to dose nitrate and i'm feeding heavy just to keep my nutrients above 0.

I have a UV in my display tank that I can use to help stop it from taking over.
