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

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

Works well with my filtration system. Is durable and I dont have to clean it so often.

Came unpluged and aquarium fogged up badly. Plugged back in and half a day later was CLEAR! Mine is 150 gallon.

Perfect fit!

This is a great filter system that works very effectively. The bio sponge fits nicely in the tray and when cleaned properly will last a long time. I change mine about every 6 months and clean it every 2 months. I have mine filtering a 45 gallon and the water parameters have remained perfect.

The Cascade 1500 is the best cannister filter Ive ever owned. These filters do a great job. I bleach mine out then soak in water with Seachem Prime.

I love the ease of replacing with just using another sponge - easy change out. My tank is so clean that I have noticed colors in my fish I never saw before.. This is obviously making a difference and I am gong to continue using this product as well as recommend it to others. I thought my filter was doing a great job, but adding this sponge has made a great looking tank even more awesome! Thank You !!!!

Perfect fit, great product!

Works as expected...

Happy
