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 ## 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.be/products/2333777-penn-plax-cascade-300-power-filter-hang-on-filter-quad](https://www.desertcart.be/products/2333777-penn-plax-cascade-300-power-filter-hang-on-filter-quad) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-11*
