I don't know what I have going on. I thought it was diatoms, but now I don't know. Phosphates test untraceable. Nitrates test under 2. Running Chemipure elite in my filter socks and ROWA in my reactor. 12 small fish under 3", except my mimic tang in a 200 gallon plus sump. Pic below is not mine, but is exactly what it looks like.
