That is the best place it could have happened. As usual, if someone with more experience comes along, listen to them, not me. But if it were mine I would stir a couple times for a couple days then leave it be. It will need to sit a while to drop lees anyway, and it will natually lose meta during that time.
What I don't understand is why you feel 1/2 tsp for 6 gals is correct. Do the instructions that came with your meta say to use that much? Mine all say 1/4 tsp for 6 gals.
I guess you can tell I haven't made skeeter pee by my questions. Hoping someone experienced with pee comes along soon tho.
