Marineland 48 pk Penguin Rite-Size C Filter Cartridge

I use them for my 65 gallon tank with two big fish and have to change filters 2-3 times per month. VPS.com is pretty much the only place I can buy filters without going broke plus their customer service is by far the best of any store, internet based or brick and mortar. I'd give them a 6th star for their customer service and quick responses to emails (Posted on 6/13/11)

I use these in two Marineland filters - two for a 55 gal and one for a 26 gal tank. One is cichlids and the other is fancy goldfish. Work great. (Posted on 3/10/11)

Easy filtering and no mess. Their prices were very cheap conmpared to buying one and two at a time. (Posted on 3/10/11)

Just wondering from users if these were the actual replacement cartridges or the fake cheap ones? (Posted on 3/10/11)

I have been keeping fish tanks for a few years now and have so many tanks and so many filters that sometimes I worry about having too much and not enough money for filters. So I shop around the internet, because fish stores sell these for outragous prices, for the best deals. And I found it here! Seriously, wish I wouldve found Value Pets 4 years ago!!!! The price is unbeatable!!!!!!!!!! (Posted on 3/10/11)

I have an overstocked 55 gal with fish that I never thought would live this long or get this big, but I love them. So I have the big filter that takes two C Penguin media. I found the best price on this web site, buying six months at a time. I have to change the media every week! Thank you for providing the right product at the right time at a good price.
