This filter pushes water at 300 Gallons per Hour (GPH) for tanks up to 100 Gallons in size. It’s great for Freshwater and Saltwater aquariums.ACCOMMODATING: The adjustable flow knob allows for increased or decreased water flow at will, which is extremely helpful during feeding times, or use it as needed.

REVOLUTIONARY: The Cascade 300 Power Hang-On Filter features a Bio-Sponge cartridge that optimizes colonization of anaerobic bacteria, and is independent from the first stage filter media. In addition, our Bio-Falls system enhances water oxygenation, and aids with removing ammonia and nitrate.OVERALL MEASUREMENTS: 8. 25” (H) x 11. 25” (W) x 6. 25” (D).

Review: Fantastic value for the cost. It’s crazy powerful yet it’s as quiet as a whisper - I decided to switch to this filter for my 62-gallon fancy goldfish tank after running a Marineland Penguin for quite some time... it was the best decision I could’ve made. The biggest pro to using this filter is the silence. It’s the quietest hang-on-back filter that I’ve ever come across. 4 months in and there’s little to no mechanical noise coming from the motor, my mother often puts her ear up to the filter because she can’t believe it’s even on. There’s also very little noise created by the water return (which I absolutely love). If you’re someone who likes to hear the sound of running water this filter will not be it for you, you can hardly hear a trickle. The filter is also incredibly efficient with a fantastic (and completely adjustable) flow rate. They really don’t lie on the box when they say this thing turns over 300 gallons of water per hour. Be prepared to have your water looking clear as day, especially when used with the right filter media. My only concern with this filter is that the materials do feel a little bit fragile, so I’m curious to see how it holds up long term. All in all though, it’s fantastic value for the cost; it’s just as good as any other mainstream brand filter out there.
Review: Perfect for customization to allow a fit on the side of a 55 gallon, or smaller! - 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.

## Questions & Answers

**Q: Hey guys, what is the voltage? does it go from 110 v to 240v? i don't see it on amazon uk. if it doesn't work with 240v, what can i do? thanks.**
A: Thanks for your question. This filter is 110V and there's no way to adjust it to 240V for England. We wouldn't recommend running this filter with a power converter, so your best bet may be to stop by your favorite local aquarium store to purchase your filter.

**Q: I always buy the replacement carbon filters but where are the 2 black replacement foam sponge filters?**
A: When I buy these filters I throw away the black foam.I used the white filter fiber works so much better..and gets your water clean and clear faster..

**Q: I have a 56 gallon tall tank and need a filter that works well in this type. Will this model work well in the tall tank type?**
A: I think you will be happy with this filter. I am using one in my 200 gal fish tank I like it because 1. it is a good filter 2. It keeps the water oxygenated. ( lot's of bubbles )  :-) when I get my 75 gal tank ready I all ready have one for it.

**Q: What is the KWH for the 300 per day?**
A: idk but its probably not anything your going to notice

### ⭐⭐⭐⭐⭐ Incredible Value
*by J***. on March 30, 2020*

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!
