I agree with matthew- wash them outside, period! Use a 5 gal pail, fill 2-3 X and youre done. No need to take the mess inside/kitchen/agitate the wife, eh??
Trace algicide in a stinkin septic tank is insignificant- wont last. Septic putrid goo filled with cagillions of bactrial cells will overwhelm any trace algicide/mildecide.
