9 Pcs Fish Pond Foam Aquarium Filter Sponge Wave Shape Coarse Foam for Fish Tank Sump Pond 17 x 11 Inch x 1/2 to 1 Inch, Black, Green, Blue

This product was smaller than expected so I had to double up on the filters. Guess it’s a good thing I purchased the 9 count not the three as I would have returned it. The online photos look a little thicker and better quality, this product is pretty thin.

The measurements say 17x11 but since it is vacuum sealed it is super small. Look at the picture for the before and after.

I recieved this product with high hopes. Upon receipt it is sealed together very tightly in a vacuum sealed bag. okay...upon opening, the ripples of the wave had been damaged by the vacuum seal and would not "fluff" back up,The cuts are also not to expectation. They are much smaller than 11x17. I have attached a photo with the measuring tape and a true 11x17x1 inch pad.The material is cheap and does not condense together the way a "fine" foam filter media should allowing all kinds of light throughThis product is not going to do the job to filter the water appropriately

Foam came vacuumed sealed. I opened it and let sit over night to expand. Still a shriveled mess. Do not purchase this garbage

Very small. There is no egg shell in the foam I'm very disappointed. I don't do this often but this was robbery.

Vacuum packed pieces of junk - never regained normal size or function

This product came totally flattened. Such a waste of money.
