Jerp - I have looked at the glass in my UV after months and there was no slime. I don't know what to tell you. I was surprised myself. Perhaps it's the heat?...
I run in and the CO2 reactor in line with a mag drive 9.5 which pushes 950gph. It's under the tank so that limits it some and there are right degree turns which also cuts down on the 950gph. My UV is an Emperor Aquatics 25 watt smart UV Sterilizer. I got it from FishtTanksDirect.com. That was a year ago. Seems to still be working fine. I wonder if it's time for a new bulb, since it's a fluorescent? Here is the link: http://www.fishtanksdirect.com/index.asp?PageAction=VIEWCATS&Category=245
