UV STERILIZERS

UV sterilizers are a versatile technology used for disinfecting water, other opaque liquids, hard surfaces and air. Using the same germicidal rays as the sun, but hundreds of times stronger, UV offers a reliable, cost effective, and environmentally friendly alternative to chemicals and their resulting bi-products. UV Sterilization is a purely physical process, not a chemical one, so it doesn’t alter water’s chemistry, taste, smell or pH levels.

Aqua Ultraviolet manufactures commercial UV sterilizers for aquaculture, greenhouses, drinking water, food and beverage industries, aquariums, medical facilities, pharmaceutical production, and municipal reclaimed water. Aqua Ultraviolet also manufactures residential UV sterilizers for home aquariums, drinking water, outdoor ponds, swimming pools, and more. Notably, we are a leading manufacturer of aquarium UV sterilizers, serving the aquaculture industry with state-of-the-art technology to keep aquatic environments clean and healthy. We also produce a full range of units for residential and commercial aquariums, swimming pools and ponds. As an innovator in the industry, our designs result in a maximized UV dosage allowing for equipment with a smaller footprint that efficiently treats higher flow rates.

FAQ

What is a UV sterilizer and how does it work?

A UV sterilizer uses ultraviolet light (around 254 nm) to destroy or deactivate microorganisms such as bacteria, viruses, and protozoa in water. The UV damages their DNA or RNA so they cannot reproduce or spread.

What are the benefits of using a UV sterilizer in ponds or aquariums?

UV sterilizers improve water clarity, reduce harmful pathogens, lower disease risk for fish, and help maintain a healthier, balanced aquatic environment.

Where should I install my Aqua Ultraviolet sterilizer?

For best results, install it after the filter so the water entering the UV chamber is clear of debris. This ensures better UV penetration and protects the quartz sleeve from scratching.

Can the UV sterilizer be installed vertically or horizontally?

Yes. Most models allow both positions. Units with a manual wiper often perform best horizontally to keep the wiper seal moist and effective.

Do I need to shut off the UV sterilizer during maintenance or cleaning?

Yes. Always turn it off if water flow will stop for more than 30 minutes or if the chamber is drained. Running the lamp without water flow can overheat and damage the unit.

How long does it take to see clear water after installation?

With the correct size unit and proper installation after the filter, clarity often appears within 3–5 days. If installed before the filter, it may take 7–10 days.

Does the UV sterilizer remove algae and particles from the water?

No. UV only neutralizes living microorganisms. It does not physically remove particles or algae already in the water. Filtration handles particle removal.

Will UV light affect beneficial bacteria?

Any bacteria passing through the UV chamber will be sterilized, but most beneficial bacteria live on filter media, rocks, and surfaces, so they remain unaffected.

How often should I replace the UV lamp?

Replace the lamp once every 12 months or after the manufacturer’s rated hours of operation (usually 8,000–10,000 hours). The lamp may still glow after that period but loses effectiveness.

What other maintenance does a UV sterilizer need?

Clean the quartz sleeve regularly to remove mineral or organic buildup, inspect O-rings and seals, and keep the unit free of debris. These steps ensure maximum UV exposure and prolong equipment life.

Can a UV sterilizer be used in both freshwater and saltwater systems?

Yes. Aqua Ultraviolet sterilizers are designed for both environments. In saltwater, clean the quartz sleeve more often to prevent salt deposits that reduce UV penetration.

Is a UV sterilizer safe for fish, plants, and people?

Yes. The UV light is contained inside the chamber and does not enter the pond or tank. It is safe for aquatic life and people when operated as directed.

How do I choose the right size UV sterilizer for my system?

Size selection depends on water volume, desired flow rate, and clarity goals. For parasite control you may need a higher wattage or lower flow rate compared to simple water clarification. Refer to the product sizing chart or consult Aqua Ultraviolet for guidance.
