Description

The Penn Plax Cascade Hang On Aquarium Filter features a revolutionary Bio- Falls Quad Filtration System to keep your tank clean and healthy. The polyfiber floss cartridge traps floating particulate matter while the activated carbon cartridge removes harmful chemicals, toxins, odors, discoloration and other contaminants from the water. The internal sponge optimizes the colonization of beneficial anaerobic bacteria while removing ammonia and nitrites. The external Bio-Falls wet/dry biological booster provides anaerobic bacteria for additional ammonia and nitrite removal while enhancing oxygen exchange for maximum water oxygenation. This hang on aquarium filter attaches easily to your tank by sliding over the edge of the glass. A leveling device keeps your filter in position and the self-priming intake tube has a built-in extendable stem to allow placement of the intake strainer close to the bottom of most aquariums. Filter includes an adjustable flow control knob to reduce filtration during feeding times or as needed, and the quiet and efficient motor is maintenance free. The Penn Plax Cascade hang on filter delivers up to 300 gallons of water per hour and is suitable for fish tanks from 55 to 100 gallons in size. It measures 11 inches high by 9. inches wide by 6.5 inches deep and is suitable for both freshwater and saltwater tanks. The Cascade Aquarium Filter Comes with bio floss and activated carbon cartridges and is ready to use.

  • Perfect for customization to allow a fit on the side of a 55 gallon, or smaller!
Size: Cascade 300
I love this unit! I was able to do a minimal customization to allow this unit to hang on the side of my 55 gallon tank! It’s small yet large enough to keep the tank clean. Perfect for filter modifications! It’s 3-4 times larger than the quiet flow 10! It’s much, MUCH quieter than the whisper EX! Enough room to add any media you’d desire to the holding/processing tank. Has a flow adjustment which would be great for more delicate fish. With a hand grinder I was able to remove 2 tabs, one from each side of the unit where the opening for the water to flow is, it wasn’t quite small enough to fit the 55 gallon side, so I took a hand grinder and cut off each tab shown in my photos, it fits perfectly into the space now and works great for the area I needed it to fit into! Happiness! PLEASE NOTE: If you appreciated this review please give it a “thumbs up/like if it was helpful” I truly appreciate you helping me to continue to give honest/unbiased insight into products I’ve used and you may have questions about. Interested in a product but don't know enough about it and would like it reviewed? Please let me know and I'll see what I can do... follow me for a vast array of purchased product reviews.

  • Incredible Value
Size: Cascade 300
I’ve been an aquarist for 50 years, so I’ve used most major brands. I needed a low-budget filter for a proof of concept - experimental stuff. This is an awesome filter. Having said that, there’s no way I’d have this in a 100 gallon saltwater tank, and very skeptical that it would suffice. This filter is quiet and well-made. It took a minute or less to assemble, and everything fit well, had a quality feel, and fit perfectly together. I used this on a 20-gallon long saltwater tank I’m using for propagating bubble-tipped anemones and the flow is just ideal. I would estimate that this filter would be very good to excellent for nano-reef aquariums up to 30 gallons (With a powerhead), and 40 gallons for fish-only saltwater tanks. I’d maybe up that to 60-75 gallons for freshwater. Other sizes, I’d still suggest this pump ...just get 2. Personally, I’d have two of these on a 40-gallon reefer, but I’m also running a low-flow powerhead too. I don’t see any negatives in buying this filter. The price is outstanding for what you get and so what if you gotta buy two...or three...it’s still going to provide quiet, excellent filtration power for your hard-earned money. UPDATE Running a few months now, doing great! ... show more

  • Shop carefully
Size: Cascade 300
Upon opening looked liked nice product but unable to review because not only did it arrive damaged but missing parts. Ther was no extension tube/tubes so couldn’t use even with broken top. Unable to contact Penn Plax no one returns calls.

  • Best under $30 HOB I've ever bought
Size: Cascade 300
Its so quiet! I bought this to replace one of my mainland 350 biowheel filters that died unexpectedly (which was loud, noisy, and rattled constantly) My tank is in my living room and I hated the marineland because I had to turn the tv volume up to hear over it. This penn plax is very, very quiet. LOTS of room for media. I kept the sponges that came with it and replaced the charcoal.with purigen. I also had plenty of space for a layer of floss. It has pretty good suction... It easily grabs anything floating within about 6 inches of the intake tube (with wavemaker off) My one and only complaint is that the intake tube, fully extended, is way to short. It works for now because I run 2 HOBs on my 75 gal but ill have to buy an ntake extension I think this is a great filter and the price is pretty amazing. ... show more

  • Good Filter With One Drawback
Size: Cascade 300
The media could not be loaded. Been using this sense Oct 2018. The filter media last extremely well, much longer than the carbon contained permanently within the replaceable cartridge. I always use two filters per tank the other filter is of a different design and I can change carbon more easily with it though the filter media sucks and life is too short. Pros: Filter media holds up well and can be cleaned and reused several times. Good water flow and fairly quiet. Cons: No way to just change out carbon without possibly damaging cartridge. A simple redesign of cartridge would make life perfect. ... show more

  • Seemed kinda cheap in the beginning. But more then makes up for it
Size: Cascade 300
So far this thing is great... Super quiet and the flow is fully ajustable. If you have a fish /critter that requires minimal currents but still need powerful filtration this is a great filter. The flow its self is fully ajustable on the unit and the "Bio falls" splits water evenly on exit across the waters surface. I bought it for a turtle tank but didn't wanna spend the money on another canister filter. I had every intention of buying another canister filter later but I've decided to move this filter to my Axolotl tank and move the canister filter to the turtle tank. And even with messy turtles this filter has been able to keep up with their bio load. The media that comes with the unit isn't the best but it's units large capacity leaves plenty of room for whatever you'd like to add. Plus the cartridges it comes with make it easy to remove the old and cut any sponge you'd like to fit if that's what you chose to do and all for a price much cheaper then many other competing HOB's. ... show more

  • not what it says
Size: Cascade 300
I got this as a quick replacement for an old quietflow 75 that stopped working after 5 years, the old quietflow would out flow this in spades, this filter would do great for like a 40 gallon, my current setup is a fluval fx-6 canister supplemented by a quietflow 75 (tank is 250 gallons) this filter does not flow well, so I do not believe the up to 100 gallons thing at all, I swapped this into a 40 gallon guppy breeder and it seems just about right for a 40 gallon tank, frankly this is the third pen plax filter I have bought in the past 10 years, still to find one that does what that company advertises. spend your money elsewhere if you have a bigger than 40 gallon tank ... show more
