When my nutrients were reading 0ppm for N and P for a week and not ncreasing with heavy feed, I was certain this was dinoflagellates.
Then, no dinos happened; well not the bad kind at least!
Is this a phytoplankton bloom?
It only reproduces when the lights are on. It’s green. When I clean the glass it goes cloudy again within an hour.
It doesn’t grow in the rocks or sand. My sump is in a similar, less worse condition as the lights are automatic when I open the door.
I set the tank up 3 months ago with dry rock, live sand. I put my old live rock in there for 1.5 months to seed the dry rock then removed it at a small piece per week. I have marine pure balls in the sump.
