Tank has 3.5 feet of material in it... looks like roughly a 4x3 square structure.
The top scum layer is like a foot thick, and it's almost physically impossible to break through it in some spots (its like a big heavy quilt). In the spots i was able to break through, i go down to the bottom of the tank and never feel a sludge layer.
It seems to me that the scum layer is blocking the inlet and pretty much preventing anything from getting to the bottom. The bottom 'feels' pretty much liquid under the scum layer.
I'm not afraid of sticking my arms down into the tank and pulling the scum layer out, if it would save me $400.
A. Is it feasible to just pull the scum layer out by hand?
B. If so, is there somewhere i can dispose of it? Like put it in big contractor trash bags or something and take it to the city dump or somewhere that would accept it?
