Aquarium UV Sterilizers Reduce Chances of Outbreaks

The application of UVGI to disinfection has been an accepted practice since the mid-20th century. It has been used primarily in and sterile work facilities. Increasingly it has been employed to sterilize and , as the holding facilities are enclosed and can be circulated to ensure a higher exposure to the UV. In recent years UVGI has found renewed application in .

Below is a video from BRS which does a good job of explaining the aquarium UV sterilizer.

UV is versatile technology used for disinfecting water, other opaque liquids, hard surfaces and air. Using the same germicidal rays as the sun, but hundreds of times stronger UV offers a reliable, cost effective, environmentally friendly alternative to chemicals and their resulting bi-products. UV Sterilization is a purely physical process not a chemical one so it doesn’t alter water’s chemistry, taste, smell or pH.

Here are a couple of ways to connect an UV sterilizer to an aquarium:

Consult with the company or pet store about the type of UV sterilizer that you need. When it comes to UV most other manufacturers will recommend a small UV Sterilizer for a large tank which really won't do much more than make your water look a bit cleaner. If your ultimate goal is to keep bacteria, protozoa, and other free floating pathogens at bay there really is no better choice than Pentair Aquatics for UV sterilizers.

To Purchase UV Germicidal Sterilizers.

Ballast/Transformer; This part of a UV Sterilizer, Purifier, etc. often does not last as long as the main body/unit itself.
This is more true of the electronic ballasts than magnetic, although the starters used with magnetic ballasts often need to be changed every year).
As well many of the low quality units that are now flooding the market often have cheap electronic ballasts that last 6 months to a year.
Poor design, care (including allowing the UV to over heat due to lack of flow while the UV is still running), or placement of a UV Sterilizer/Purifier can also prematurely destroy an otherwise good ballast.

The video below demonstrates the repair of a UV Sterilizer body:

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.The effectiveness of any UV sterilizer is determined by the UV bulb wattage, the age of the UV bulb, how clean the quartz sleeve is and the flow rate of the unit.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.In other words, UV can be very effective in reducing free-floating microalgae, bacteria, fungal spores, and microbes in general, protozoan parasites in the free-swimming stages of development, and other suspended microorganisms (Fenner, 2003a). Seahorses are prone to a number of serious bacterial problems such as Vibriosis and mycobacteriosis, and a properly installed and maintained UV sterilizer can be invaluable in reducing the incidence and spread of such infections. When properly used, UV sterilization can reduce microbial levels in the aquarium to the low levels normally found in the wild or below (Fenner, 2003a). But it doesn't kill organisms that are significantly larger than microbes.
