Cleaning a UV sterilizer for aquarium use is also essential. Cleaning the quartz tube of “slime” every 4-6 months and changing the UV bulb once a year is recommended.

For pond UV applications (or high flow rate aquariums such as sump systems) it is usually best to have a ‘T’ with a ball valve to split the return line to the pond from the filter, this will allow the aquarium/pond keeper to slow down the flow to the UV to the correct rate as per gph and wattage.
This method will allow the proper flow through your UV Sterilizer while maintaining flow rate with the remaining filter system with no added back pressure. This is better than adding just a ball valve which will add back pressure and then also slow flow rates making the filter system less efficient I continue to follow the threads on forums, aquarium articles, and blogs about UV Sterilization.

The aquarium UV Sterilizer is a water filtration device that uses an ultraviolet light bulb to kill microscopic organisms that are free floating in the water. Parasites, viruses, algae and bacteria (good and bad) are the type of things that are "killed" after passing through the ultraviolet sterilizing unit. UV sterilizer devices can be used on swimming pools, in liquid factories (think beer) and in the home aquarium using an aquarium UV sterilizer. Some large water purification centers employ some sort of UV sterilization on the outgoing water. These sterilizer units are also sometimes used in outdoor ponds to help control algae growth and they seem to do a decent job.Aqua Ultraviolet’s UV Sterilizers have been used by public aquariums, importers and hobbyists alike to control bacteria, protozoa and parasites, reducing the spread of fish disease. In a confined environment like an aquarium UV and filtration are essential. When using a UV Sterilizer in a home aquarium, the UV unit should be placed last in the filtration line. You want to first filter the aquarium water through your and then run the water through the UV device before returning the water to your fish tank. By first removing the solids in the aquarium water with your mechanical filter (canister filter, etc), you are helping your UV unit to attain maximum operational efficiency.We review our top 7 Best UV Sterilizer For Aquariums that we feel are worth a mention, each covered in detail with helpful information on how they can benefit your tank.It still amazes me how much misinformation is spread about this, some masked in science. As I have stated many times before, a UV Sterilizer is not essential for any aquarium, however even for goldfish I have maintained tanks with, and many other variables, I have noted a differences because of the sterilizer. Many times this has lead me to a thriving tanks.The Best UV Sterilizer for Aquariums is one that can kill as many bacteria and microorganisms as possible, and that is exactly what we are going to help you find.
