I run bio-pellets and zeo (AA + Coral Vit) and also run UV 24/7 in my sump. If I had extra space on my controller's power bar, I would run my UV off of it so that it only came on part of the day.
I do dose Zeo during my feeding cycle while the return is off.
Sometimes I'll unplug the UV for a few days or so.
I know I do have Ick in the tank as one of my tangs and a mandarin have shown spots before. I've never had a full outbreak.
I am seeing the benefits of Zeo and Biopellets. I assume due to the lack illness in my fish, the UV along with my regement of supplements (garlic and selcon) are keeping them healthy.
