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 2900 gallons per hour for the 40 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.
