Convenient and no mess

Usually we buy the "assemble-it-yourself" box with filter pads and sealed foil packs of charcoal to put into the filter pads. But that can be tricky and messy when not if you spill charcoal, and it's nice to have the complete filter insert ready to go. And much, much quicker. We liked the price, too.

These carbon filter are perfect for my turtle tank and also my fish tank. They are easy to rinse in between replacing them and changing them is super easy and efficient.
