Directions Follow included paper instructions. 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.

Thank you 🙏 Review: Great filter at a low price - Works well and does the job. Fairly quiet you might hear a slight hum and the trickling of water. Can't be beat if you're in the market for one and can't be beat at this price. ## Features - QUIET & EFFICIENT: The Cascade 300 Power Hang-On Filter quietly delivers crystal clear water throughout the aquarium.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for customization to allow a fit on the side of a 55 gallon, or smaller! *by S***E on 26 October 2019* I love this unit!

Can't be beat if you're in the market for one and can't be beat at this price. ### ⭐⭐⭐⭐⭐ Awesome filter *by T***Y on 1 March 2025* I have 2 of these on my fancy goldfish tank. They work great. My only issues with this filter is the small gap between the bottom of the cartridge chamber and the cartridge insert. I feel that the bottom should be completely flat so the cartridges sit flush on the bottom. Otherwise I love these filters. Very quite and easy to use and clean. ## Frequently Bought Together - Penn-Plax Cascade 300 Power Filter – Hang-On Filter with Quad Filtration – Great for Freshwater and Saltwater Setups - Penn-Plax Cascade 300 GPH Hang On Replacement Media for The Cascade 300 Filter, 3 Pack - Penn-Plax Cascade 300 GPH Hang On Filter Aquarium Bio Sponge Replacement; 2 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/53290988-penn-plax-cascade-300-power-filter-hang-on-filter-quad](https://www.desertcart.ph/products/53290988-penn-plax-cascade-300-power-filter-hang-on-filter-quad) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-08-14*
