UV is working hard!

You can tell the UV is working!! Intake hose is green and outflow hose is crystal clear! Got the skimmer repaired and running again. Corals are mad about something but don’t ask me, haven’t made any drastic changes and water parameters stable.

Biofilm build up on intake, nothing left alive to build up on the return.

That was kinda my point, that the UV was working since the outflow line is clean
