Uv Sterilizer

UV Sterilizer

A UV-C bulb in a flow chamber that kills free-floating parasites, algae spores, and pathogens - improving water clarity and disease resistance.

Price: Mid For: Both $60-$500

📖 Overview

UV sterilizers expose water to short-wavelength UV-C light. Pathogens passing through the chamber - including free-swimming parasites, algae blooms, and some viruses - are destroyed. UV improves water clarity dramatically (green water clears in 24-72 hours) and provides an additional disease defense layer.
