Whisper Bio-Bag Refill Cartridge

Got it on line,alot cheaper,plus they don't carry it in the store.

This is the best price EVER!!!! I work at a pet store and I've found them to be too pricey. I happened to stumble upon them on this site and I'm soooo happy. We all could save a little money and buy them from Walmart.com!!

Have been using this product for years. After shopping the Internet for this product I found the best price at Walmart on line. It was delivered site to store in a timely manner. I will use this service in the future.

Is very efficient and product lasts longer for one use than one would expect. My fish tanks stay cleaner for a longer period of time which makes me and my fish very happy.

Now I have had fish tanks since i was 4 and I'm 26 now so I know a lot about fish. And one thing i know is this bio wheels are great but dont have much surface area so the best is whisper. I love whisper the prices are pretty cheap to start with compared to the bio orb witch is like 10 bucks a filter these are dirt cheap!!! but for ten buck to get twelve i cant find them under 15 bucks at the local petco!! I got 2 boxes for 20 bucks 24 filters 2 years worth of filters for the cost of a lunch at a resturaunt!!!!! I love walmart only buy this here now cheap as heck like ebay but 100000xxxx more convient!!!!!!!
