GUARDMAN Filter Foam Sponges, Bio Sponge Filter Media Pad Cut-to-Size Foam for Aquarium Fish Tank Pond Filter Open Cell Foam Sheet Filter Cartridge Media Sponge

I use this to help reduce splash on my fountain by smoothing out the initial water stream at the top as it cascades down several tiers. Easy to use and cut in any shape.

I needed A replacement filter for a power supply on a piece of electronic equipment. I couldn't find anything that was made from the same material. This filter looked similar, so I took a chance. Not only was it the same material, but also the same thickness. I just cut to size and was all set.

I just cut to thr size of my filter to build up a little extra bio on to transfer to a new tank. Worked great!

The foam pad is not square and it’s cut kinda wonky, but it’s filtering betta poop, so it’s fine. Great filter medium for my dramatic little fishy dude.

I’ve saved myself so much money buy purchasing these filter sponges as opposed to buying pre-cut prices designed to catch dirt. I highly recommend purchasing these if you use a pet water fountain, they prevent dirt from entering the motor flows the water.

Highly Recommend! These pads are super easy to cut and much are bigger than I thought. They don't have a smell, and seem like they'll last a lifetime. Happy fish, Happy wife, Happy life!

I was hoping 30 ppi would work in my project. The pictures made the pores look larger than they were.Didn't work for me.....

It’s easy to cut, no odor, using them in my existing filters and as a prefilter. Would recommend!!
