What kind of UV sterilizer is it? I'm just wondering about the possibility that it needed some rinsing out first.
Did you have cloudy water before? I used mine to kill green water and the first day the water changed hue just a little but didn't clear up for like 4 days. I think it killed the algae the first day but resulting color change was minor.
