Penn-Plax Cascade 1200/1500 GPH Canister Filter Aquarium Bio Sponge Replacement; 1 Pack

Gfy

Very pleased, works great.

Does it’s job. Just pricy.

Works great and fits perfect!! It’s a great filter! Would purchase again!

Perfect

So far so good . I added these to my filtration system for my turtle tank.

Works as advertise. I think its even better quality then the stock one used for cascade filters.

Needed to improve the effectiveness and efficiency of my filtration system. So I added an additional Bio Sponge. Guess what? I think I saw my Green Terrors smiling at me!

The listing on Amazon said there were two sponges, but there was only one. Very pricey for two, but for a single? Way overboard. I like the convenience of the sponge, and the fact that it fills the entire cartridge with no mess. But it is not worth the extra money. Back to the filter bags filled with loose carbon for me!

great
