Aqua One 93s Outlet Sponge - Protein Skimmer G216,G220, G224

A new 93s Aqua One Outlet Sponge for all G Series Protein Skimmers. The Foam prevents the return of fine undesirable bubbles to your marine aquarium and should be washed regularily to maintain water flow. After a few months of use and washing the cell structure of the foam starts to collapse and it needs more and more cleaning. This is the time to replace the foam with new pieces.
