I ordered one grit guard on amazon and they accidentally sent me two, hahaha!
They were wedged together and looked like one piece. My guess is; whoever packed my order up, doesnt know any better.
But yes, 2 grit guards in a 2 bucket system are better than one.
To the OP, WOW, I have never seen sludge like that after a wash.
