A UV sterilization system is a handy little device for keeping your fish tank healthy and free of diseases. If you want to keep your fishes safe and your tank in top shape, UV sterilizers are a must-have.

There are also many benefits to using a UV sterilizer in your tank. UV sterilizers help keep your tank looking and smelling fresh, kill bacteria and stop algae from forming, act as a physical barrier to prevent snails and unwanted debris from being sucked into the filter, and can help reduce the amount of new bacteria that is introduced into the water, which helps to prevent over cycling of the filter.

Frequently Asked Questions (FAQ)

Which is the best UV light sanitizer?

UV C Sterilizer- This, in my opinion, is the best UV light sterilizer currently on the market. It is a little more expensive than the other two, but the UV C light kills bacteria, germ, and virus 99.99% of the time for up to 2 hours! This is the best UV light sterilizer for sterilizing water for long periods of time.

Whole House Ultraviolet Water Sterilizer- This UV light sterilizer can be placed anywhere in your home that you have an electrical outlet. It generates the same ultraviolet C light that the UV C Light Sterilizer does. It is built to kill bacteria, germ, and virus in water. It is not built to sterilize water for long periods of time.

Do UV sanitizers actually work?

The answer is yes and no. It takes 10 minutes of exposure to harmful bacteria to reach a “Virus On” state. Regular soap will kill bacteria within a minute or two. So UV lights only save you a few seconds but in a world where cleanliness is important, that can make all the difference.

In fact, UV sterilization is used by the military and restaurants. They say that it is the fastest way to clean up and studies conducted by sanitation experts concluded that it is the most effective way to get rid of bacteria.

What will be the UV sterilizer for you or your family? Let’s find out.

Are UV sterilizers worth it?

A UV sterilizer works by irradiating water with ultraviolet light, killing bacteria that cause waterborne diseases. This process is called ultraviolet disinfection or UV disinfection. They are used in commercial water purification at water facilities.

As a result, drinking water from a UV-disinfected system is safer than relying on chemicals alone to remove pathogens. Water, when subjected to UV-C light, is changed into a form that is not sustainable for microorganisms. This forces such pathogens to mutate or die.

The advantages of UV sterilizers are:

  • they generally faster than other purification methods
  • they do not require chemicals for purification
  • they do not remove beneficial minerals, such as calcium, chlorine, and magnesium

They can be used on virtually any water container (e.g., lakes, rivers, fog, swimming pools, and aquariums)

How long does it take for a UV light to kill bacteria?

The length of time it takes for a UV light to kill bacteria varies with the intensity of the UV light, the overall surface area of the bacteria and the thickness of the surface being treated. Far-UVC is the wavelength of light that’s used in high-output UV sterilization. This wavelength has the ability to penetrate into the actual cell walls of bacteria, fungi, and yeast but does not penetrate into human skin or tissue. This enables the light to continue to kill germs on items for a long period of time in relatively low light. It is important to remember that UV light does not reduce the bacterial concentration but rather has the ability to kill bacteria, viruses, and spores that are present. UV light is effective at killing germes, but it will not remove them so a thorough clean and disinfection will still be required.
