Just thought it was time for a new one. ### ⭐⭐⭐⭐⭐ Good product, be aware it is sold individually *by J***B on May 22, 2012* Just an FYI, each package only contains 1 sponge (filter floss comes in a 6 pack). . . This perfectly fits the trays inside the cascade 1200 and 1500 canister filters. The sponge is quite coarse and will catch the biggest debris particles. However you'll want a tray or two loaded with filter floss to polish the water. As for maintenance of the bio-sponge, there's really no reason to replace this product any sooner than once a year. To clean it: pour the old canister water into a bucket, then take and wring out this "biosponge" in there. Wash it off using the old aquarium water and once it's fairly clean, put the sponge right back into the filter. Don't use city tap water to wash this because the chlorine will kill the beneficial denitrifying bacteria. I say 5 stars out of 5 because it perfectly fits the filter tray, the price isn't outrageous, and it will last a really long time. ## Frequently Bought Together - Penn-Plax Cascade 150 or 200 GPH Hang On Filter Aquarium Bio Sponge Replacement; 1 Pack; Cut to fit Cascade 150 or 200 - Penn-Plax Cascade Hang-on Power Filter Replacement Cartridges - 3 Pack - Penn-Plax Cascade 200 Power Filter – Hang-On Filter with Quad Filtration – Great for Freshwater and Saltwater Setups --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/13002061-penn-plax-cascade-150-or-200-gph-hang-on-filter](https://www.desertcart.pl/products/13002061-penn-plax-cascade-150-or-200-gph-hang-on-filter) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-06-04*
