UV sterilization treatment requires clear quartz sleeves to be placed around the UV lamp, acting as a barrier between the water and the bulb. Over time, mineral deposits and impurities in pond water build up on the outside of the sleeve — reducing UV transmission and sterilization effectiveness. Regular cleaning or replacement every few weeks keeps your system performing at its best.

Why Quartz Sleeves Matter

The quartz sleeve is one of the most critical components in any UV water treatment system. A compromised sleeve means reduced UV output, which directly impacts water clarity and the health of your koi. Keeping a spare on hand ensures you're never caught off guard.
