Aquarium UV Sterilizers
UV sterilizers work to keep your tanks cleaner longer by removing free-floating algae, and reducing bacteria and pathogens that find their way into your aquarium. They can either be fully or partially submerged in the water. We recommend putting them somewhere easy to reach, preceded by the biological and mechanical filters so the water entering the sterilizer is as clear as possible. The bulb will need maintenance or replacing from time to time. At Petco, we have water sterilizers, UV and LED replacement bulbs in various wattages for big and small tanks. UV sterilizers are a must-have component in your aquarium, whether you’re a new fish hobbyist or a master aquarist.
In addition to a wide range of UV sterilizers and parts, Petco has everything you need to keep your tank clean. This includes products dedicated to water care, and aquarium cleaning supplies such as brushes, nets and cleaners for every stage of tank maintenance. You can even use a gravel vacuum to clean the base of your tank more often. Cleaner tanks make for happier fish. And less maintenance makes for happier fishkeepers.
FAQs About Aquarium UV Sterilizers
Check the instructions that come with the UV sterilizer you purchase—each system is a little different. Though it’s a good idea to ensure your tank is set up near a power source, as your UV sterilizer will require electricity to function properly.
UV sterilizers help control pathogens in your aquarium and remove free-floating algae and bacteria. A UV sterilizing system keeps your aquarium cleaner, so you won’t need to clean your tank as often.
That depends on your budget, how you plan to maintain your tank, and the size of your aquarium.
We recommend positioning the UV sterilizer in an easy-to-reach place in your tank, preceded by the biological and mechanical filters. The UV light needs to penetrate the water to be effective. As such, the water should be as clear as possible when it enters the sterilizer. Also, you’ll likely need to replace the bulbs and provide routine maintenance to the sterilizer, like cleaning any film or mineral deposits on the lamp.
Most aquarium UV sterilizers need to run 24 hours a day in order to do their job. Review the instructions that came with your unit for additional guidance.
