Zilla-Replacement Filter Carridges Medium-3 Pack 09830

This is the third box I purchase but this time most of the filters were quite empty of the black carbon. One of them had less that 1/4 of it covered with carbon.

Two out of three filters only lasted a week and a half, I have a red eared slider and understand they can be messy, the third filter in the box lasted about a month not sure why so Imgiving it a second shot and ordered another box of three. I will update this review to let everyone know how long the new box lasted.

No returns, even though I received the wrong size.

We love them for our red eared slider buddy!!

Great product

quick delivery, as described

Keep the tank clean.

This is the third time buying these medium an d they are smaller than the previous.
