Description
The CNZ CUV-136 36-Watt External UV Clarifier is an inline, non-submersible water treatment unit for ponds and large aquariums up to 8,000 gallons. Designed to operate externally between your pump and main biological filter, it handles up to 660 GPH flow to eliminate free-floating green water suspended in the water column.
Heavy-Duty High-Volume Water Clarity
Keep large outdoor ponds, koi displays, and water gardens looking pristine. The CNZ CUV-136 utilizes a 36-Watt 2G11 4-pin UV-C lamp housed inside a high-transmittance quartz glass sleeve. As water is pumped through the spiral housing path, the ultraviolet light beam physically breaks down organic particles that cause green water blooms and persistent murky haze.
