Lived in house for 5+ years with no problems. Now rent the house out and every 8-12 months there is thick, white clumps and build up causing float switch problems (multiple overflows). The matter is not waxy or greasy so I wouldn't call it "sludge". It's hard but can be broken apart by hand and floats. The problem with the float was that this stuff built up on it and it's size caused the float to get wedged between the tank wall and the piping. For clarity, it did NOT seem to keep the float submerged due to lack of buoyancy.
Anyway, looking for help to identify what this stuff might be and get some guidance to some solution. I've seen what grease can become in this type of setup and it doesn't fit with what I'm seeing here.
Only one bathroom in basement (sink, shower, toilet) flow into this tank; no laundry, no kitchen sink.
Picture shows the float on the left covered in the white, chalky substance.
