Aqua Ultraviolet is one of the most popular options available and has been in the UV game for more than four decades creating UV sterilizers for use across multiple industries including aquaculture and food & beverage on the commercial side to aquariums and ponds for home use. They're simple in construction, well built, and they're made in the USA. 


How UV Sterilizers Work

Ultraviolet sterilizers are a time-tested approach to water clarification and sterilization. They emit a germicidal UV-C ray that will alter the DNA or RNA of single celled organisms like algae, bacteria, and protozoa, rendering them unable to reproduce. The result is crystal clear water without the use of any chemicals. Using a UV sterilizer will not alter water chemistry. 

Aqua Ultraviolet sterilizers include a clear-blue cap that lets you see when the lamp is powered on, without having to risk any exposure to the harmful UV-C rays. How effective the UV sterilizer is greatly depends on having the proper flow rate through the sterilizer body, so we highly suggest using a valve or a DC pump to control the flow through the UV sterilizer. For freshwater aquariums, AquaUV suggests 700 gallons per hour for the 15 Watt Classic UV Sterilizer. 



Over time the efficiency of the sterilizer will start to diminish because the lamp is no longer putting out the same amount of energy, but also the quartz sleeve that houses the lamp can become coated with mineral deposits and start to become cloudy. We suggest cleaning the quartz sleeve a few times each year and replacing the UV lamp annually. This AquaUV Sterilizer includes quick-connect unions on the input and output allowing you to quickly remove the entire system from your aquariums plumbing for maintenance. With proper maintenance, your UV sterilizer will work like it did from day one.

What size do you recommend for a Red Sea 350?
Question by: Kenny Etter on Apr 3, 2024, 2:39 PM
Hi there, thanks for the question! It is always recommended to oversize your UV. I would recommend the 25W for a Red Sea 350 at least.

I’m looking at 15 watt classic UV sterilizer in the details at top it says flow rate 233GPH
further down it says saltwater application 466 to 700 GPH
I’m looking for a UV sterilizer for a xl 200 Red Sea that will be housing seahorses
Would this be a good choice and what flow would I want
Thanks for any help
Question by: Don on Mar 19, 2022, 7:25 AM
Hey Don, thanks for the question! I would suggest the 8 watt UV as this will likely be enough for you. The different applications are specified for algae control vs protozoan. Protozoa Bacteria Water Flow Rate: 214 (min), 642 GPH (max)

The picture shows a stepped barb fitting. What are the 2 sizes of the barbs as well as the NPT size?

Hey Dwain, we appreciate the reach out! The barb fittings included with these Classic UV's is a 3/4" barb x 3/4" NPT. The stepped portion should allow you to also attach 1/2" tubing if neccessary!
