Buy Penn-Plax Cascade 700/1000 GPH Canister Filter Aquarium Bio Sponge Replacement, 1 Pack at desertcart UK. Review: Great - Great Review: Good product, be aware it is sold individually - 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. ## Features - Filter sponge optimizes the colonization of beneficial aerobic bacteria which prevents the water from becoming cloudy and harming fish. - Perfectly cut to fit into the Cascade 700 / 1000 filter tray without any gaps ?which could allow pollutants to re-enter the water. - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002DJD4O | | Batteries Included | No | | Batteries required | No | | Best Sellers Rank | 199,631 in Pet Supplies ( See Top 100 in Pet Supplies ) 1,506 in Aquarium Filters | | Colour | Original Version | | Customer Reviews | 4.7 4.7 out of 5 stars (1,478) | | Date First Available | 9 Aug. 2012 | | Item Weight | 0.28 g | | Item model number | CCF229 | | Number of Items | 1 | | Product Dimensions | 19.05 x 3.81 x 13.97 cm; 0.28 g | | Quantity | 1 | | Size | 1pk | | Specific Uses | Indoor | ## Images ![Penn-Plax Cascade 700/1000 GPH Canister Filter Aquarium Bio Sponge Replacement, 1 Pack - Image 1](https://m.media-amazon.com/images/I/81oBp0mjDtL.jpg) ![Penn-Plax Cascade 700/1000 GPH Canister Filter Aquarium Bio Sponge Replacement, 1 Pack - Image 2](https://m.media-amazon.com/images/I/81GvOHI7fsL.jpg) ![Penn-Plax Cascade 700/1000 GPH Canister Filter Aquarium Bio Sponge Replacement, 1 Pack - Image 3](https://m.media-amazon.com/images/I/618Fogb511L.jpg) ![Penn-Plax Cascade 700/1000 GPH Canister Filter Aquarium Bio Sponge Replacement, 1 Pack - Image 4](https://m.media-amazon.com/images/I/81XVRSlGw7L.jpg) ![Penn-Plax Cascade 700/1000 GPH Canister Filter Aquarium Bio Sponge Replacement, 1 Pack - Image 5](https://m.media-amazon.com/images/I/81PtCQznCnL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by M***I on 17 November 2019* Great ### ⭐⭐⭐⭐⭐ Good product, be aware it is sold individually *by J***B on 22 May 2012* Just an FYI, each package only contains 1 sponge (filter floss comes in a 6 pack). . .
