A UV Sterilizer can help you to keep on top of fish tank maintenance and helps protect the health and wellbeing of your fish. In this article, you’ll learn more about these accessories and we’ll share some of the best units you can buy.
A UV sterilizer is a device that you can install into your aquarium to eliminate the growth of harmful microorganisms. Wondering how it works?
To put it simply, this unit releases UV rays from a light bulb, which filters the water that passes through it. This way, it gets rid of a lot of unwanted microscopic organisms such as:
This useful device can be utilized in many scenarios. You can use it in your at-home fish tank, in large aquariums, and in swimming pools.
It also does a pretty good job of controlling the formation of green algae in ponds. Algae can be quite annoying when it gets out of hand, which you’d know if you’re an aquarist.
Choosing the right ultraviolet aquarium filter for your fish tank can be quite challenging, especially for beginners. Therefore, we’ve decided to include the following list to help you figure this out.
This UV sterilizer by Aqua UV has all the features you’re looking for – it’s pretty pricey, and not for a novice, but it can be worth the cost.
For starters, it can sterilize up to 1,200 gallons of fresh water and about 150 gallons of saltwater. Therefore it’s great for larger fish tank setups, rather than small ones.
Not to mention that it comes with a few characteristics any aquarist would appreciate. For instance, the unit weighs about 5 lbs, making installation and maintenance a piece of cake.
In fact, all the parts that make up this device can be easily twisted apart for quick maintenance. Also, the whole device is designed to withstand maximum flow rates, which further enhances its performance.

If you want a budget-friendly option for your small or medium-sized fish tank, we highly recommend this UV sterilizer. Unlike the previous device on our list, this unit is vertical using the drop-in installation style.
It also doesn’t depend on any pumps to do its work, being gravity-fed and all. This might explain its relatively low wattage, which is 11 watts.
Its UV cartridge, which includes the light bulb and the quartz sleeve, is disposable. Therefore, you can easily remove it to replace any of these components or for maintenance purposes.
All in all, this simple UV sterilizer can be one of the best units to install on the back of your little aquarium.
Finally, we’d like you to have a closer look at this UV sterilizer. We think it can work perfectly in smaller fish tanks, especially those with a maximum capacity of 30 gallons.
There are other reasons to like this device. For example, its UV lamp can last for approximately 5000 hours. Also, its distinctively compact size makes it submersible. Therefore, you can connect it to your existing water pump and hide it out of sight.
The last thing we like about it is that it can be used with both fresh and saltwater.

When To Start Using A UV Filter
There isn’t a specific time that you need to begin using a UV sterilizer. Yet, there are a few points you need to keep in mind before turning it on. For instance, you should install it as a final piece of your filtration system. It shouldn’t be considered a replacement for a filter or for regular water changes.
Plus, you shouldn’t use it when you first cycle the aquarium. This is because it’ll kill the beneficial bacteria, which you’ll mostly want to keep for the wellbeing of your marine life.
Also, you should turn it off when you drop medications into the water. See, the UV light can break the bonds in those treatments, which defies the whole point. In addition, the UV light might change the nature of these medications, which can be harmful to the inhibitors of the tank.
How To Choose An Ultraviolet Sterilizer
If picked correctly, this unit can provide a reliable degree of protection to your aquarium against unwanted visitors. Therefore, you must pay some extra attention to the following points.
Aquarium Size and Water Flow
The sterilizer model must match the dimensions of your aquarium. To do that, you’ll only need to check the manufacturer’s size requirements.
Still, despite how large your tank is, the water flow is another factor you should consider. See, your aquarium might not be the biggest out there, but the water speed can be fast, which will change the scales. Therefore, before making up your mind about a unit, make sure that it has both points fulfilled.
The power of the UV bulb that you can find inside an aquarium sterilizer is determined by wattage. Thus, the higher the number is, the more efficient the unit should be.
We’d also like to point out that a higher wattage means that the bulb’s ability to produce UV light might dim with time. For this reason, you can expect to replace this bulb every six months or so.
There are plenty of aquarium UV sterilizer styles out there. Some come to be installed horizontally, while others are vertical. There are also types that you can hang on the back of the tank; others can allow you to submerge them in the water.
The options are endless, to be frank. Therefore, you should make your decision based on the type of aquarium that you have.
UV Sterilizer Aquarium
To preserve the health and wellbeing of the plants or animals in your aquarium, you should provide them with the ideal ecosystem. One of the most important devices, alongside accessories like a protein skimmer (for reef tanks) or an osmolator, is a quality UV sterilizer.
Our top pick is definitely the Coralife Turbo Twist UV Sterilizer. We love it for its reasonable price, easy installation, and long bulb lifespan. Not to mention that it can be used for both fresh and saltwater.
