This website has the best prices I have ever found for Marineland filters. Marineland filters work great. I have never had a problem with them. I even use them when medicating the fish. I just cut the top of the fuzzy part and throw out the carbon, so that the tank stays clean while the fish are sick.

We aquarium enthusiasts, know how much money will, and can, be spent each month. Especially when it comes to filter cartridges. Pet stores charge obscene amounts of money for filter cartridges, and even this brand. They do not sell them in even number packs, which is very annoying, and very costly. For the price of 1 RITE SIZE; size C; at a pet store, you can buy 6 packs at PETMOUNTAIN.COM for only a few dollars more. It's completely worth it. 6-12 weeks worth (depending how often you change). They are just as good as the name brands, if not better. Another great thing about RITE SIZE is they are not only compatible with Penguin brand pumps, they are compatible with just about any pump. Believe me! Check the pet stores for the RITE SIZE cartridge you need. Measure your existing cartridge if need be, then go to PETMOUNTAIN.COM and save a LOT of money!!! NO JOKE! -Zzakarya, dedicated Petmountain.com customer

I am so glad that you carry ths product and what a great price. Minimum shipping cost is too high and a real turn off.

I ordered 36 filters since the price was a great deal and they don't require special storage. My aquariums look dazzling with frequently changed filters--about once every 6 weeks.

Great filter for great price.

The best possible way of getting the aquarium to filter out garbage but keep the levels as close to as normal without constantly changing pH or other additives!

Product is OK. However, longevity has been abbreviated by design change. How about doubling 6 package to 12 and reducing cost once again?

I have shopped online for years for a lot of pet products and Pet Mountain is by far the best, cheapest, fast service. Never a problem with orders. These cartridges are great. Easy to use.

I have been using these for many many years!!! I am so happy with this filter system and they do not disappoint me ever!

Since I found Pet Mountain I buy all my filter media from them. Their prices save me about 50% over what my local pet stores charge.

With any Marineland brand filter you can be just assured that it meets the highest of quality standards. Ive been using them for over 5 years now.

I like using the Marineland filter cartridge for my filter. Just pull it out and throw out in the trash. No more that 5 minuets and you are done with fuss or muss!
