A UV sterilizer is an essential piece of equipment for your tank.
It improves water quality…
… by killing germs, parasites, and algae floating around.
Through its sterilizing action, it helps filtration.
AND prevents the spread of infections.
It has even been known to stop many diseases dead in their tracks!
From all models out there, the Aquatop in-line UV sterilizer stands out.
Read our review to find out…
… if it is the right aquarium UV sterilizer for you.
The Aquatop In-Line UV Sterilizer is a compact device, allegedly designed for aquariums of all sizes.
It serves both amateur and light professional use, but it could be a better choice for the former.
Lightweight and easy to install, it comes equipped with a 10-watt UV bulb.
A flow rate of 211 gallons per hour ensures adequate sterilization of a small or mid-size tank environment.
It might not be a top-end unit; nonetheless, it comes with multiple benefits…
… and at a price that won’t break the bank.
I initially tried this sterilizer on a 29-gallon system.
Now, I use UV sterilizers on all small to mid-sized tanks due to its versatility and installation ease.
Sure, it’s not perfect. It has some limitations and drawbacks.
All in all, though, this is undeniably an excellent in-line UV sterilizer for starters and hobbyists.
For really tiny tanks, a smaller 5-watt variant is also available from the manufacturer.
Aquatop In-Line UV Sterilizer is a simple yet capable device.
Don’t expect bells and whistles, but it has what it takes to keep your water pristine and system healthy.
From a purely aesthetic point of view, it presents itself as a standard UV sterilizer tube. It can be easily integrated into any filtration line and, according to the manufacturer, even in submersible pumps.
I wouldn’t recommend submerging it, though (eek).
Indeed, using it with a canister or sump filter system would give better results…
… while prolonging the unit’s lifespan.
The sterilizer has a thin composite body that isn’t the thickest.
However, the choice of this more affordable material helps maintain the overall costs accessible.
I really like how easy it is to install.
The sterilizer comes with three different-sized sets of barbed fitting for different applications.
Perfect to install vertically or horizontally; it also comes with a bracket for attaching to a wall or cabinet.
Features & Functionality
This aquarium UV sterilizer is designed to work with small and big tanks alike.
According to the manufacturer, it’s a great choice for freshwater tanks of up to 200 gallons or saltwater tanks of up to 70 gallons.
Despite the manufacturer’s recommendation though, I wouldn’t use it for tanks bigger than 40-50 gallons.
The reason is the water flow.
Bigger tanks usually have more fish.
Which means they need higher water flow for the filter system to remove fish detritus effectively.
However, this UV sterilizer is rated for a maximum water flow of 211 gallons per hour.
Thus, using it in a big tank would result either in poor overall filtration if you slow down water flow or in ineffective sterilization if you use it at a higher rate.
Before deciding on this unit though, also consider your purpose.
This UV sterilizer won’t kill viruses and bacteria if the water flow through the unit is higher than recommended.
Nevertheless, I found that if you’re only concerned about floating algae, the unit does an excellent job at killing them at higher water flow rates too.
It doesn’t come with a powerhead, but it’s compatible with most canister and sump filters.
And in the end, the only things to pay attention to are how you install it and the water flow.
Indeed, I’ve heard many people complain about the unit not working or doing a poor sterilization job.
Nevertheless, I love the Aquatop In-Line UV Sterilizer because I had realistic expectations from the moment I bought it.
This device doesn’t cost hundreds of dollars, so you can’t expect it to work as a high-end tank sterilizer would.
Set the water flow too high, and you’ll never be impressed with its performance.
Expect the bulb to last for over a year, and you might be disappointed to find that it needs replacement after 6 months.
Set realistic expectations, and you’ll love it.
The barb fittings usually fit perfectly on most powerheads and pumps; I had no issues with the leaks, but if there are any, the problem is easy to solve with a bit of Teflon plumbing tape – the material is both reef and goldfish/freshwater fish friendly.
Sure; perhaps you’ll have to deal with some leaks.
Maybe you’ll have to change the bulb sooner than expected.
Or maybe you’ll even find the material flimsy.
Considering its price, though, I wouldn’t mind these small downsides and possibly the little extra work that might be required to seal it properly.
