Price is great and the cartridges work as they should. My toddler niece and nephew refuse to get it in their heads that they can’t feed our betta fish because over-feeding will kill the fish—I think they just like the snow globe effect the food has when it falls/moves through the water. Their mom left them unattended and the kids dumped the entire canister of food in the one gallon aquarium!! (I’m waiting to have the budget for something bigger) Thankfully the fish didn’t over-eat and didn’t choke on the horrifically dirty water while waiting for a water and cartridge change to happen.

These filter cartridges are the only ones that fit the fish tank we just bought with a built in filter. The filter is so quiet you can't even tell it is on. The water is crystal clear. I couldn't find this exact size of these filter cartridges anywhere else so thank you to Chewy for making them available!
