As an aquarium keeper, both new and experienced, you’ll already be well aware of the importance that keeping your tank water clean is when it comes to looking after the health and wellbeing of your fish and plant life. It’s essential.
The chances are you’ve already got yourself a filter for this exact reason, but regardless of whether you’re keeping a freshwater or saltwater aquarium, bacteria always seem to find a way in which can encourage microorganism growth which will quickly overtake your tank.
If you’re experiencing a lot of problems in this area, it’s safe to say you’re going to need more than just a traditional internal filter and will instead require a UV sterilizer.
This is a mechanical filter that will work alongside your traditional filter to ensure it will stay as free from harmful pathogens as possible, drastically enhancing the quality of your tank water.
Sounds like the right tool for the job? Today we’re going to explore five of the best UV sterilizers out there, as well as talking about everything you need to know in order to choose the one that’s right for you and your tank.
AA Aquarium Green Killing Machine 24-Watt Internal UV Sterilizer System with Power Head
To start with, we’ve chosen the Green Killing Machine from AA Aquarium. The reason it’s called this is that it’s specifically designed to target bacteria and microorganisms that can cause algae which can damage your aquarium water quality.
Not only does it target the larger, more noticeable forms of tank pollution, it can also target the smaller entities, ultimately ensuring your tank water is crystal-clear with your fish and plant’s lives taken as a priority.
The simple reason we’re started with this sterilizer is the fact it’s the number one selling UV sterilizer in the US with over half a million units sold across the country. This is all thanks to the patented and exclusive UL and UV technology this pump has that you simply won’t be able to find with any other pumps.
In terms of safety, this UV sterilizer is pioneering the industry. The bulb itself is stored in a secure environment which means you or your aquatic life will never have to touch the glass itself. Even when you’re installed the pump, there are so many reports this takes less than 10 minutes, ensuring you’ll be up and running in no time at all.
As you can see, we can go on and on all day about the many amazing features this sterilizer has. From quick-change bulbs with a control panel that tells you when they need changing, a 3-year warranty and the fact it comes with four filters to keep you going for many months, does it get any better than this?

Ideally, you’re going to want to implement this UV sterilizer into a tank that measures in around 50 gallons or less, which is still pretty big when you look at a list of common household tank sizes. This is in comparison to other AA Killing Machine that supports tanks up to 120 gallons in size.
