Eshopps Square Large Foam - 13 1/2 in. x 4 in. x 2 1/4 in.

I bought this after upgrading my sump pump and with the increased flow, it created microbubbles and it filled in the gap. Not only did stop the bubbles but helps with filtration.

Foam block is smaller than adveritizied. As a result it does not fit the space and water bypasses foam block. Would not purchase Eshopps products again.
