For those Koi and pond enthusiasts who are not as careful as they might be, we do also sell the spare Delta Replacement Quartz Tubes.
The Delta Quartz Tubes insulates the lamp from the water, allowing the lamp to operate at the optimum performance.
The ultraviolet lamp will remain independent of the flow of water. Delta Quartz Tubes are of open at one end only and are made from pure fused quartz.

Quartz is extremely transparent over a wide spectral range, with a low coefficient of thermal expansion and quartz is resistant to scratching and thermal shock. Fused quartz is made form crushing and melting natural materials. The purity of quartz is paramount to the efficiency of the lamp and sleeve.
