UV-13 13W

The Resun UV-13 is a submersible internal UV clarifier and sterilizer featuring a 13W UV-C bulb, designed to provide effective water purification for medium to large aquariums up to 400 liters. Placed fully submerged inside the tank or sump, this self-powered unit incorporates a circulation pump that continuously exposes water to the germicidal UV bulb. It efficiently eradicates green algae spores, cloudy white bacterial blooms, and floating pathogens without affecting the beneficial filter-bed bacteria.
