Aqueon Quietflow Internal Filter Cartridge Large 4Count

It's a good filter and I clean them out to use them a few times.... I even took one apart and put in a sponge to save money. There expensive! The only thing I don't like about the filter is the price.... and unfortunately, I don't have any other purchasable options for the filter and these work way better than what I can make my self. So...yeah. Expensive but good. A little too expensive. I've been buying these for about a year. Buying them in big packs is the way to go.

Filter cartridges work well and overall pleased with the entire product, both filter and replacement cartridges. Despite having replaced them within my filter twice now, there is a slight trick to knowing which pieces go in what order with the tabs, etc. Therefore, I highly recommend that you keep them in the same order when pulling them out so you know how to put them back in, otherwise the top does not fit properly.

This water filter was recommened with the water pump purchase. These are size large filter replacements, but i ordered a small water filter. Why would Amazon recommened an item that's the wrong item.... my fault for not reading more carefully before processing items in my order. I can't even excgange the large filters for the size i need as "this item can't be exchanged or retuned" according to Amazon return/exchange policy. Ultimately disappointed with my whole purchase, water pump and all.

This product is wonderful. I have not went to the pet store since buying this product online. I paid double in the petstore verses this deal online. This product is the same as in store and works the same. The only difference is price. I recommended buying this product online.

I have a turtle, which requires me to change the filters monthly. Being able to buy 2 at a time is very helpful.

We have some very intestinally healthy fish. I was worried that they would clog up too fast, but they seem to be handling the volume of poo fairly well.

Bought this to replace the filters on our fish tank. Perfect replacement product! It was also cheaper that going to petco.

Even watching tutorials it is easy to put this together the wrong way. On the up side they are easy to clean with a faucet sprayer so you can reuse them
