Dinos?

[Xadieu]

I believe i'm having Dino-flagellates problem, I was wondering if anyone have left overs of Fauna Marin Ultra Algae X bottle in Calgary. I'm seeing signs of it such as brown stringy strings, a film over my snail shell, rocks and some corals. It's not much right now but i want to get it under control before it becomes a problem.

Nitrate is reading 0 and phosphate is reading 0.02 ppm with hanna checker in case anyone is wondering.
