Product Description

Aquatop CF300 3-Stage Canister Filter, 264 gph

Aquatop CF-300 Canister Filter

The CF300 is one of our most popular canister filters and you really can't beat it for the price. The 264 GPH multi-stage filtration system is ideal for fresh and saltwater aquariums ranging in size from 20 gallons to 75 gallons. The CF300 defies its low price because it comes equipped with all the necessary plumbing for installation and includes three large filtration media compartments allowing you to add the filtration media of your choice. The filtration media trays offer a fully customized filtration system to suit your specific aquatic needs. The CF300 includes three 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 CF300 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 CF-300 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. * U. V. Sterilizing Unit not available in CF300 but assembles and filters in the exact same manner as the CF-400 and CF-500*

I bought this filter because I originally had my eyes on the Cascade 1000. This filter has about the same GPH (265 vs. 264) for half the price. When I first removed it from the package I was greeted with a product that appeared to be used. There were some light scrapes, and moisture. Enough moisture that I actually found mold inside the canister. All the tubing, intake, outtake, etc. appeared to still be sealed though. Not sure if this is the distributor's (TruAqua), or the manufacturer's fault.

After cleaning it up it is working great though. I've had it running for about 5 hours now on a 55 gallon, with a sand substrate, and my water has cleared up a lot. It came with plenty of filter media to fill up the three trays as well. Plastic Bio-balls, Activated Carbon, Filter Cotton, and what I'm assuming is Ceramic for more beneficial bacteria to grow on. The pump for priming it was also nice, made it super easy to set up.

I highly recommend this if you don't mind receiving something that appears to have been used. Maybe I was just unlucky, but it is still a great bargain despite this.

It seems that the filter media isn't included with this system anymore. They updated pictures to show notes on the media saying that it's not included instead of updating the description.

For media I've been using Marineland Rite-Size filter pads that one has to cut to the proper size. As well as activated carbon, and ceramic, but I just get whatever is on sale when I need more.

At the current price of $80 with no media included I can no longer call this thing a bargain. I personally purchased this for $50 with media included. When I wrote half the price of the Cascade 1000, I literally meant half the price.

Starting a new 55 gallon aquarium can be quite expensive. I wanted to do things right and not get 'soaked' in the process (sorry, bad pun!) After doing a great deal of research on filter types, I knew I wanted a canister. I had a bit of sticker shock while shopping around. Then I found this product!

My order was processed quickly, even delivered sooner than I anticipated. I had the unit put together and running in no more than 15 minutes. Getting it assembled was effortless. I was completely shocked at how silently it operates!

As I write this review, I am looking at my new little fishy family, swimming happily in their new home.

I highly recommend this product to anyone looking for great value, prompt delivery and a very effective filter.

My fishies thank you, and so do I!

264 GPH?????? I'm replacing a Penn Plax Cascade 1000 on my 46g bowfront with this. Not for any reason, because the Cascade 1000 still works well after 6-7 years (gaskets are a little worn and tubes are filled with gook). To compare, the Cascade 1000 spray bar is longer and has more pressure coming out of it (Penn Plax is rated at 265GPH). The Cascade 1000 is larger, has a handle, and comes with all the filter media. This external filter is much smaller, has about 80% the spray output, and comes with white floss on the 3 provided trays, and a bio sponge on the bottom tray.
Next, the priming pump. Doesn't work unless you fill the filter up with water. After you fill the filter up with water, it works fine. The Penn Plax primes an empty canister.
Noise? Quiet as can be. I can't hear it at all. Penn Plax is just as quiet.
Hoses? comes with nice green (Eheim type) hoses, and not the cheap hoses that comes with the Fluval 306.
Is it worth sixty dollars? YES
Will you be happier with a Penn Plax 1000 for a little more? Yes, also considering the Penn Plax comes with the filter media.
Overall, it's cute, does a fair job, and is not too heavy to carry to the kitchen sink.
Do I feel safe with this unit? Yes. the connections are tight, and everything fits perfectly together.
Overall well made, but if you're looking for a lot more power, I'd choose the Penn Plax 1000.

Edit: to add, I think a lot of people are complaining about water in the filter when they received the filter. I found drops of clean water in the filter, and chalked it up as the company was testing to make sure the filter is in working order. Hopefully, someone from the company will respond.

edit: to add again-after changing the filter I noticed the canister can be assembled wrong.

I setup the canister last night without too many issues. Initially it ran whisper quite but has since developed a vibration noise that I will have to figure out tonight. The media trays are a good size but they are made quite cheaply. The media trays are very securely seated in the canister and almost impossible to remove without damaging the popup handle on them. In fact both lower trays already had the handle pop off. I have to figure out a way to remove the trays without relying on the handle. I may need to grease the outside of the tray to see if that helps.

The media included is ample but I wish it came with a better mechanical sponge filter or foam batting for the lowest tray. Also it would be nice if the input bar and spray bar came with some external bracing as I am having a hard time getting it to rest nicely on the back of the tank.

But so far I am happy with the performance per price ratio
