I am in Palm Beach County and have seen worse pool messes after the
hurricanes.

You can clean up just about anything short of a septic tank with these
ingredients:

Low pH (pool acid)
Chlorine up to 10 ppm (sodium hypochlorite in the jugs)
Pump and filter running for days
Polaris 180, 280, or 380 to do the vacuuming

This may be a stupid question but - is there a drain for a pool?
