The sterilight UV system only requires annual maintenance. While the effectiveness drops as the bulbs age, the unit includes a computer readout that tells you exactly how many days until you need to change the bulb and an audible alarm goes off if the UV output is insufficient to sterilize the water.
So you don't clean the quartz tube more often?

Which unit are you talking about? The ones I've seen the lamp is on full time, water moving or no, which is why the lamp is rated at 9,000 hours, or just about a year. If it's on full time, at Big Island electric rates, I figure 48 watts will cost nearly $200/year for power , which isn't a huge amount, but it's not nothing.
