Description
Aqua Ultraviolet Classic UV Sterilizer
Achieve crystal-clear, healthy water with the Aqua Ultraviolet Classic UV Sterilizer. By utilizing a high-efficiency UV-C wavelength, this system targets and disrupts the DNA and RNA of single-celled organisms, effectively eradicating free-floating algae, harmful bacteria, and protozoa without the need for chemical additives.
Designed with versatility in mind, this unit features a large housing to maximize water contact time with the UV lamp. Whether you are aiming to clear up cloudy tank water or control pathogens, you can fine-tune your results by simply adjusting the flow rate using a gate valve or DC pump. This 57 Watt, 2" slip version is built for larger reef systems, big-volume ponds, and higher-flow plumbing setups that outgrow the 25 Watt unit.
Key Features:
- See-Through Efficiency: A clear blue quartz cap allows you to visually confirm the lamp is powered on without risk of UV-C exposure.
- Simple Upkeep: The EZ-Twist cap ensures quick, hassle-free quartz sleeve maintenance.
- Plumbing Freedom: Quick-release unions on the input and output allow you to remove the entire system for service without tearing down your plumbing, meaning you don't need extra clearance for bulb or sleeve replacements.

Why Buy Your Aqua Ultraviolet Sterilizer From World Wide Corals:
- We run UV on our own systems. Aqua UV sterilizers keep water quality high across our own coral holding and grow-out systems every day.
- Sizing help from people who actually keep corals. Not sure if the 25 Watt or 57 Watt unit fits your system, or what flow rate matches your sump and pump? Our team can walk you through it so you order the right unit the first time.
- Bundle and save. Add your UV sterilizer to your next coral or dry goods order and consolidate shipping — something a standalone UV retailer can't offer.
- Real support after the sale. Questions about lamp replacement timing, quartz sleeve maintenance, or troubleshooting a flow rate issue? You're talking to reef keepers, not a generic call center.
- Trusted by hobbyists and public aquariums worldwide.
