Just leave it alone. What were/are the nitrate levels? and what else are you testing? For the red Slime, most likely Cyano, try lights out for 3 days. No food, no light. I put a towel over my tank. Fish will be fine. After the 3 days, do a 15-20% water change. Slowly reacclimate the tank to the light as well. couple hrs first day, longer 2nd then full lighting by the 3rd day back
