While cleaning out my Stockman overflow silencer I noticed this thing in my overflow everything is sealed up so I can't get to it I know the little bitty Critters are sponges but what is this thing?
The next three pictures are zoomed in going from bottom to top
Not sure if this picture will help but it's from the bottom of the Overflow looking up to the bottom of this whatever it is.
