AquaTop CF500UV Canister Filter Features
Supports up to 175-Gallon Aquariums
CF500UV is designed to support aquariums with up to 175 gallons of capacity. Combined with a flow rate of 525 gallons per hour, this aquarium filter should clean your tank rather quickly. And if your fish tank is smaller, shoot, you should see results even faster.
Multistage Filtration System
CF500UV has a 4+1 filtration system. This filter includes 4 filter media baskets plus a UV sterilizer, which together make that 4+1 filtration mechanism. Thanks to the 4 filter media baskets, you could set up CF500UV any way you want.
Each of the baskets comes with top carrying handles, which allow for their easier removal from the filter during maintenance. The handles are somewhat delicate though and could also suffer from debris buildup during filtering.
Unfortunately, AquaTop CF500UV comes with only mechanical filter media from the manufacturer. That may not be sufficient to ensure the complete filtration of your aquarium water.
To be precise, AquaTop includes 4 foam filters for fine debris and 1 coarse sponge filter for larger debris. At this price point, it is typical though that canister filters come with minimal filter media.
So you if you need chemical or other biological filtration, you will need to buy that on your own.
UV Sterilizer Lamp
Now we get to the reason this canister filter stands out! The switchable 9W sterilizer UV lamp is the main reason many people choose CF500UV.
It is designed to eliminate germs and algae from the aquarium water. With 525 gallons per hour being cycled and zapped with UV rays, bacteria and algae should be a thing of the past. Note that algae formation could be caused by a variety of reasons. So if algae is still a persistent problem, look for root causes of algae. A UV light can only do so much!
Like the majority of modern aquarium filters, CF500UV comes with an auto priming feature. Instead of siphoning the filter manually, you do it by pushing the large button located at the top of the device.
While the button priming is certainly more convenient than manual siphoning, it also requires some effort, so keep that in mind.
Many users praised CF500UV for its exceptionally quiet operation. Once you get it running, it should not produce any significant noise that would disturb you. If a quiet aquarium filter is a thing you are looking for, then CF500UV may be an ideal choice.
Adjustable In/Out Nozzles
What adds to the degree of CF500UV’s versatility is the swiveling input and output nozzles on the valve assembly. It will allow you to angle the hosing a bit more conveniently without having to flex it too much.
Although swiveling nozzles can be very useful. If you will be putting the filter under the aquarium, it is nice to have some more setup flexibility.
