What kind of lighting do y'all have on your sump. I know a few here have the clamp on light fixture wondering what kind of bulbs your using for macro growth.
I use this bulb from Home Depot. I think it's 14 Watts. The light is on 24/7 on the refugium. Cheato grows like weed. I put a baseball size cheato ball about 2 months and last night I threw away this much. See picture below.
