Cool, its good to know that their is a generic filter for the peguin. Now i can pick up filters while i'm shopping at walmart. I still may check out the drsfostersmith.com option, will see.
Do they sell the ready to use media as well or do you have to use bags and assmble yourself when its time to replace? OR do you just have to buy another complete shell/media product?
Just picked up Aqua Tech filters for my Penguin for (3 for 6.12) at walmart. They are the same ones as the marineland brand. I decided to rinse out the old ones one more time to reuse.
