I am having the same problem with one of the tanks and have to say that I don't have high nitrates either. I'm in the 15-25 range using a calibrated Hach kit. I splurged and bought a UV and have it installed, but I think I have to turn down my flow much slower than I currently have to get proper exposure. So far, I can't say I see much of a difference after 4 days of UV. Before the UV, it took 4-5 days to get thick on the glass, seems to be doing the same thing now with the UV.
