Review on HAQQI Prefilter Compatible Replacement Aquarium by Leah Ramirez

These sponges are not as described or pictured in the product description. Firstly they are open at both ends so are not an aquarium pre-filter and do not match the photos in the listing. Secondly, six of these sponges were shipped in a ziplock plastic bag barely big enough for two, they never recover after hours of freedom from such restrictions. When stretched, the inner hole fits snugly to 1/2" PVC (0.84" OD), which is 1/4" smaller than the listed size. I also had trouble finding the correct pre-filter on Amazon .
