AquariumUVSterilizerFeatIn the movie Finding Nemo, the Tank Gang worked all night to make their aquarium green and dirty but was completely surprised to find their tank squeaky clean in the morning. How did that happen?

Well, Peach, the Starfish, gave a factual answer – it’s a UV Sterilizer!

Indeed, this machine that eradicates algae, fungi, and other water contaminants in any type of tank has become the ultimate hi-tech answer to any aquarium-keeper’s woes.

No more fears of fish infection, no more murky waters, and no more sudden algae blooms.

An ultriviolet (or UV) sterilizer not only complements the effectiveness of routine aquaria maintenance but brings fish-keeping to a whole new level.

It is a technological innovation that was not enjoyed by fish-keepers of the past generation and now makes life much easier for people who loves caring for their fish but are always hounded by the thought of losing them to some micro-organism that invades the aquarium.

How It Works

The cleaning process using high-intensity UV light is definitely far better and much more effective than the usual water filtration because it kills micro-organisms or pathogens that may cause harm to your fish.

Water-borne bacteria are eradicated by the UV light by altering its cell structure (or DNA). In scientific terms, this process is called irradiation which does not have any effect on the fish but can be nasty to bacteria and other microbes.

Things To Consider

Now that you know what an aquarium UV sterilizer does, your next question might be,

As any responsible fish owner would do, you should first do a little research on what type of UV sterilizer would be a best match for your aquarium.

These units come in different sizes to match different flow rates and tank size. You may refer to the below Table to check which UV Sterilizer would best suit your tank.

UV SizeBarbed FittingsFlow RateAquarium Size (Gallons)
9W1/2 or 5/8100 - 200 gphup to 125
18W5/8 or 3/4200 - 400 gphup to 250
36W3/4 or 1-1/4400 - 1200 gphup to 500

There are three types of UV sterilizers in the market today: the quartz-lined tube type-dry bulb, the tray type, and the non-quartz line tube type-wet bulb.

You must consider as well both the physical features of your tank and the type of fish you’re keeping when choosing the style of UV sterilizer you’d like to have.

There’s the hang-on unit that you can conveniently hang over the back of the tank; and the in-line unit that you can submerge and attach to your main filtration system. Both the in-line or hang-on units are available in most pet stores.

    I tried the recommended one on that American Aquarium Products page. Not only was plumbing a pain, but the unit started leaking after a month of use. Had a bad seal. Manufacturer never responded when I contacted them about it. I am now skeptical about all of his reviews.
