Yup slime/cyano. You have a nutrient issue, are you over feeding? Could add a powerhead in there to get more flow. Do you have chaeto in the sump to help eat up some of the excess nutrients?
Fuge has chaeto and your looking at the highest flow area in there. That's where the water enters the DT. No way I can add more flow. I'm going to remove the rubble and clean it out. See if that helps
Your right though. I'm def feeding to much. Both corals and fish think this calls for another WC, ugh!
