Product Description

The CF500-UV takes UV canister filters to the highest level. This 525 gph, 4+1 filtration system is ideal for fresh & saltwater aquariums up to 175 gallons.

Includes all filtration media
Includes Built-In UV!
Why the CF500-UV Canister Filter?

The CF500-UV defies its low price because it comes equipped not only with a UV Sterilizer but all the necessary plumbing for installation and includes four large filtration media compartments allowing you to add the filtration media of your choice.

CF500-UV Filtration

The filtration media trays offer a fully customizable filtration system to suit your specific aquatic needs. The CF500-UV includes four fine filter pads (white) and a single coarse filter sponge (blue) for enhanced Mechanical Filtration. With the addition of AquaTop’s Premium Activated Carbon, Ceramic Rings, or Bio-Balls (each sold separately), you’ll achieve superior filtration and crystal clear aquarium water. The CF500-UV Canister Filter has a convenient Prime Pump that eliminates the need for manual siphoning. Say good bye to a mouth full of aquarium water.

How does the CF500-UV Canister Filter work?

Unfiltered aquarium water enters the CF Series Canister Filter and passes by the U. V. Sterilizing Bulb flowing down the stack of vertical cylinder cutouts to the bottom of the CF Filter. Then water is pushed up through the filtration media compartments; the bottom compartment first, the middle compartment second, and the top compartment third. The filtered aquarium water then returns from the CF Canister back into the aquarium. For optimum performance, replace your filtration media with Genuine Aquatop Replacement Media

Having been keeping fish for 40 years, I grow more passionate about the hobby as time marches on. I also have become much more critical of the overwhelming sub par equipment that continues to flood the market.

A long time eheim fan, I've used their filters almost exclusively for thirty plus years and will always consider them the finest made aquarium filters in the world. That said, it was with some trepidation I ordered the Aquatop 500. I had read good reviews on the fish forums and decided to give this unit a shot.

Aquatops are made by SunSun one of the largest filter manufactures in the world. Aside from minor cosmetic differences this is the exact same filter as Reaction, Grech, SunSun, The Marineland C series and others. Although Aquatop is relatively new to the US SunSun has been making filtration systems since 1985 and I would encourage anyone to visit their web site.

Regarding the Aquatop 500 - I was impressed from the get go. This is one powerful filter that provides more bang for your buck than most others in this price range. Quality touches include 3/4 inch clear green non kink hose. Secure lock down brackets for the power head, a very good quick stop for leak free disconnects when you want to add media or clean the filter, a 9 Watt Quartz tube encased integrated UV which you can turn on and off from the filter head.

9 watts of UV is is pretty close to being useless above 40 gallons. Quartz covers for UV bulbs aren't cheap - the average price for a Quartz replacement tube on a 9 watt UV bulb is around $50-60. Because UV bulbs are expensive as well and usually need to be replaced every 6 months or so.

After reading product reviews from several different brands of canister filters, I was skeptical to try any of them. I decided on this Aquatop CF500UV canister filter. I have a 55 gallon tank with 1 goldfish 10 inches long, 5 goldfish ranging between 4-6 inches long, 2 bala sharks 4 inches long, 3 neon tetras, 1 pleco 13 inches long and 1 pleco 5 inches tank is overstocked to say the least! Having the majority being big goldfish, you can imagine what my water quality was like.

I was running a 60 gal power filter w/standard filtration media, a 30 gal power filter with just ammonia reducing chips, a current maker, an air strip, and a heater. I've done water changes after water changes, and when that didnt control my water issues, I spent about $200.00 in additives which was only a bandaid on the fact that I have too many dirty fish crowded in the tank, nothing could keep up. My water tests came back consistently ridiculous, and its a wonder how the fish have even survived thus far.

I ordered this canister filter on Thursday afternoon and it was at my gate on Friday morning (didnt pay any expedited shipping). It even got here sooner than the other items I ordered through Amazon Prime at the same time, and you know how crazy fast those things arrive. I set it aside and planned to dive into it the following week to give myself time to research exactly how to do it since I knew I wouldnt be getting any help from the guys on this one.

Went to feed my fish Monday morning only to find the main filter had burned out sometime overnight and the water was even yuckier than ever. So... here we go - I had no choice but to get this canister filter up and running THAT DAY!

***UPDATE 2 years later***

Well looks like the price went up since I lost bought it, but still the unit has been running fine for 24/7 for the last 2 years. Cleaned the media of fish gunk only twice since I bought it. Have it running on a 60 gallon tank with 6x6" goldfish, 1x9" pleco, and 4x3" danios. No water problems at all. Fish are healthy and happy as can be. The spray bar still sucks, and I cracked it moving it around when adjusting some new decorations for the tank. So I had to redo it with something else I concocted. It's kept up with my eheim 2217 I have on another tank just fine.

*** Original review below ***

I am new to the hobby of keeping aquariums. After much research through websites like plantedtank and aquarium central I decided upon buying this canister filter. I wanted the bigger version although the smaller ones are also great for smaller tanks I hear. I wanted a good quality filter, that has a decent track record of longevity, ease of use, and won't break the bank. Many users on other aquarium enthusiast based sites have had these filters for almost 5 years now running strong, although under different names for this product which was originally called SunSun, then Perfect, then Grech, and the final incarnation to stay is Aquatop. That was a decent enough track record to me to order this filter despite how leery I was about all the product name changes.

One thing to mention from the get go. TruAqua and Amazon are shipping out "pre-tested" units I think. They come with water in the unit and some black crud sometimes. I personally do not like this as I want everything as sterile as possible when I receive a product like this. I am not sure of the tank conditions they are testing this unit on before shipping it to me.
