IceCap In-Sump 27w UV Sterilizer

The IceCap In-Sump 27w UV Sterilizer steps up UV output for larger in-sump systems, giving chemical-free control over free-floating parasites, algae spores, fungi, bacteria, and protozoa as water passes through the chamber around the bulb. A clear viewing window lets you check the bulb without disassembling the unit. Power: 27 watts Best for: mid-size in-sump installations needing stronger pathogen and algae control than the 18w model Install: in-sump, with a clear inspection window for the bulb The viewing window is a genuinely useful feature — you can visually confirm the bulb is lit during routine maintenance checks without opening the housing. Compatible replacement parts: UV bulbs and quartz sleeves for the 27w In-Sump Sterilizer.
