7 Best Aquarium UV Sterilizers for 2020 Reviews

The little fishies (for others, larger than that) in your aquarium need a clean habitat in order to survive. Perhaps you already use a filter. And perhaps you’ve been relying on it for quite some time.

However, did you know that a regular filter doesn’t actually work to the extent of exterminating bacteria and algae build-up with much precision? Leftover algae can attract bacteria back into it, making your next cleaning day even more painstaking.

It’s time to switch from a conventional filter to a more efficient, high-tech aquarium UV sterilizer! Say goodbye microorganisms, dirt, and grime, for good, and let your little fishies swim in crystal clear water!

What Is An Aquarium UV Sterilizer?

This is the question of the century. An aquarium UV sterilizer does what a filter can, but much, much more. Its UV sterilization mechanism cleans. Yet it doesn’t stop there. Not only does it get rid of dirt particles and grime, but it also eradicates the presence of bacteria.

That makes a squeaky clean AND safe aquarium for your sea-born friends.

Moreover, the best aquarium UV sterilizer isn’t just for home use. And this is your tell-tale sign of its quality. It can be used for larger areas such as factories and manufacturing facilities that have liquid-concentrated processes. Plus, if you want to let your swimming pool be purified and spotless, this product will definitely do the work for you.

How Does Aquarium UV Sterilization Work?

The best aquarium UV sterilizer emits ultraviolet light that targets microorganisms and deals with them by causing destruction in their DNA. For this reason, it’s a more permanent method of clearing your aquarium of bacteria and other microbes that are harmful to your pet fish.

Also known as a prophylactic, it will safeguard against the further growth and spread of disease-causing germs, algae, and other forms of parasites.

The Upsides And Downsides Of Using An Aquarium UV Sterilizer

Benefits

It’s maintenance for the long-term. An explanation for why aquarium owners have difficulty looking for the source of why said habitat becomes easily murky and causes water species to fall ill and have a shorter lifespan— inability to sterilize and kill bacteria.

Therefore, the best aquarium UV sterilizer’s benefit is to cleanse and eliminate microorganisms, algae, and parasites, and stop them from making a second trip to your aquarium.

By the way, don’t be afraid of the word UV. It’s true that large doses and specific levels of ultraviolet light can pose danger to living creatures. In contrast, the best aquarium UV sterilizer utilizes a very low and safe dosage. Nothing to worry about here.

Drawbacks 

Compared to traditional filters, the best aquarium UV sterilizer usually takes quite a while before their prowess in clearing water has some form of effect. A week or so, at least. Then again, remember that a traditional filter only temporarily gets rid of gunk and grime, whereas sterilizer kills bacteria and ascertains that aquarium water is beautifully lucid for longer.
