This is a coarse pre filter sponge for filter intakes. This bridges the gap between the small and large sponge filters. Working best on most mid sized hang on back filters. Half inch hole for filter intake. Can stretch a bit if needed. Our pre filter sponges are closed on one end to prevent fry from being sucked up.

Intake hole: 1/2 inch

Diameter: 2 1/2 inch

Length: 3 inches

Perfect

These collect all the junk floating around and still allow plenty of flow. They also dont need cleaned every 3 days like my old pre filters did. I love it

What a great idea!!

I'm a former fish store owner and wish these had been available back when, a great way to increase biological activity in your aquarium simply by sliding these onto your intakes. I could list numerous benefits of pre filters, but just take my word for it, you need and want these in your aquariums!

Awesome product!

This is an awesome addition to make any filtration more effective. In combination with a hang on back filter with bio rings, also from Aquarium Coop. Incredible to finally have a sponge with the bottom filled. Can’t find one anywhere else and happy to support the store!
