ALEGI 2 Pieces Aquarium Filter Foam Sponges Pad 20 PPI, Fish Tank Bio Sponge Coarse Sheet Filter Media Pad, Cut-to-Size Foam for Pet Filters

Filter for Bissell shampooer dissentigrated, replaced with this had to cut to fit but worked perfect.

These came in a package where they were all shrunk down - instructions to let sit out or sit in water and dry - I let them sit out and then put them in water - plumped right up to the exact size I needed. These four sheets will provide a lot of replacement water filters for my cat’s automatic watering filter. Love it - can highly recommend!

Exactly what as described. Great quality and works very well.

I bought this about 3 years ago and this is my first time having to rebuy more sponge to replace the old ones. Didn't expect it to last that long. Easy to rinse out in tank water. Much better for your tank than carbon filters. I would recommend using filter floss with this though because it doesn't filter out all the tiniest particles that can make your tank cloudy. Definitely good for holding good bacteria though.

This stuff works great. Cut to fit it the way you need it it’s not real thick. You have to cut a couple times to get the thickness but it works great does what it supposed to.

Not a lot you can say, doe's it's job.

These you make a decent foam to pack a hang on back filter but they are not a pourace or open cell as what I had hoped. Guess I will stick to A-CoOp for this priduct.

Like others have said it's vacuum sealed and thin/dense when you open the bag. I just run it under warm water and wring it out a few times. It expands to the 1 inch thickness advertised in just a couple minutes.

Perfect. Rinsed in water, 20 minutes in dryer to expand, 2 sheets as promised.

The cell size is about the perfect tradeoff between bacterial growth and flow. I'm using a Sunsun canister filter with 3 layers, first is floss and this sponge, second is this and bioballs, third is ceramic rings. Before putting this in it was just hte floss, then balls, then rings. Getting the floss down to a small layer for screening and replacing half the bio balls with this sponge about doubled my flow and feels like the right tradeoff to make since the floos choked the filter so much the water is actually cleaner with a lot less of it.Also using it in a small internal filter for a 3g cube with snails. Keeps the snails out of the impeller and with a bit of floss again, keeps the water fresh.Would recommend for whatever, it's a good size for canisters, can be cut for other stuff and, good sized cells

Used them for the filter. Loved them they were great !
