Medium filter cartriges for the Whisper Filter
Keeps my little ones happy and their tank clean.
These bio bags are awesome and I really like the 12 pack, it lasted me 6 weeks. You can even use these in a reptofilter. I use it in my woodland deco fliter.
The filters were good. Work fine. It's nice not having to buy boxes of only 3 in a box now. With 2 tanks going I go through a lot. Thanks.
Great Price. Just what my fish needed. Affordable price, I checked everywhere and this was the best deal. The shipping was on time. Sticking to this site from now on. Thank You!!! =]
A package of 8 sells for $13.99 plus tax at my local pet shop. Received a box of 12 for $7.99 at Pet Mountain. Enough said.
Good product, fast shipping, no problems.
I have always purchased these. A little inconvenient to assemble, but they are way cheaper than the preassembled ones. We have 2 aquariums that use the Tetra PF10 Pumps & water clarity is great.
I have been using these filters for two years now, and I have to say the are the easiest, no-fuss filter media to change. It's just a matter of adding the charcoal to the new filter bag, remove the old dirty filter, and slide in the new. These filters also keep my water crystal clear.
Our fish tank filters arrived promptly, were easy to assemble and are easy to clean. The price is very reasonable for these packages of 12, which are not available locally. We are glad to have a good supply and not have to buy 1 or 3 at a time at a much higher price. Only problem - the cat likes to pull them out and shred them.
I replace my filter every month and this product makes that change over as easy as 1-2-3.
