IceCap 27w High Output UV Sterilizer (OPEN BOX)

IceCap Ultraviolet Light for Clarifying Aquatic Environments for Marine and Freshwater Systems Up to 140 Gallons

Key Features:

• Secure mounting brackets included
• Optional molded hose barbed fittings for easy installation with 1/2", 3/4", or 1" flexible hose, and can be trimmed to fit for maximum flow capacity
• Can be plumbed using standard PVC fittings
• Kills most suspended bacteria and viruses in the water column when run at proper flows for sterilization*
• Improve redox balance in the aquarium or pond
• Aids in the control of parasites by reducing numbers and improving the immune function of aquatic life

Ideal For:

• Reef and marine hobbyists who prefer UV sterilization integrated into their return line or external plumbing rather than drop-in sump installation
• Systems of 140 gallons and above where the In-Sump UV Sterilizer models are undersized
• Hobbyists recovering from a disease outbreak who want reliable inline UV sterilization at a rated flow

Pro Tips:

• Match wattage to tank volume before buying. The 27W is rated for marine tanks up to 140 gallons, the 40W up to 400 gallons, and the 90W up to 1,000 gallons. Running an undersized model on a larger system will significantly reduce sterilization effectiveness.
• Do not exceed the rated maximum flow rate for sterilization. Flow rate determines UV contact time. Exceeding the rated GPH reduces the UVC dose delivered to the water. For disease treatment, run the unit at or below the rated sterilization flow, not the maximum clarification flow.
• Replace the lamp at 10,000 hours regardless of visible output. T5 UVC lamp output degrades well before the lamp stops glowing. Mark the installation date and replace on schedule. A lamp that appears lit is not necessarily still delivering effective sterilization.
• Keep the quartz sleeve clean. Mineral deposits reduce UVC transmission through the water. Inspect and clean the sleeve at each maintenance interval. Replacement sleeves are available if deposits cannot be removed without damaging the surface.
• Have a spare lamp and sleeve on hand. When the lamp reaches the end of its life or a sleeve cracks, having replacements immediately available avoids downtime in a running system.
• Never look directly at the glowing UV bulb while it is powered on. When testing your wiring or verifying that your new 90W ballast is firing up correctly, never plug the electrical cord in while the bulb is sitting exposed on your workbench. The high-output germicidal light emitted by this lamp outputs high-frequency shortwave UVC radiation. Looking directly at this raw light beam for even a few seconds can cause immediate and severe ocular burns, retinal damage, and painful skin irritation. Always make sure the lamp is fully inserted and sealed inside the black polymer vessel before restoring electrical power.
