Aqueon Filter Cartridge Medium Size 24-pack

These work like a charm. Buying them here is a MUCH better value that finding them at a fish store.

Works well and instantly

Fits nice and snug.

I trust Aqueon & these work great- have a 30 gal with a small aqueon filter operating beside a larger Tetra or Petsmart 20+ gallon filter uses different cartridges- I like how easy the Aqueon ones are to pop in & it’s a real workhorse- 2 giant fantails plus a giant pleco n small pleco and assorted other tropicals

Fish tank filters. I have used this brand for several years and am very satisfied with the Aqueon product.

Great filter at a bulk price is a winner all the way around. If you do the math on the filters its cheaper to buy them like this in bulk packages instead of the smaller packages.

very happy.

These were the most economical buy for us for our aquariums. I cannot believe what brick and mortar stores here were charging. Though these were still pretty pricey, these were the best per filter. Since we have a medium filter these are the cartridges we buy. They work well and keep your tank crystal clear! I wash them when they are dirty and use them for about a month’s time. I will buy again!

Great

Definitely great to buy this product from amazon. Such cheap price for the same product... so save some money for other aquarium supplies
