Two things: first, thanks for the chuckle. I have never heard of "Enchanted Shock," but it brought a smile on a bleak day. Yes, it was just a typo, but it was a
funny typo to be sure.
Second: NEVER toss in capfuls of anything. ALWAYS measure. Go to the store and buy a plastic measuring scoop which measures dry ounces. Just about all chem bottles have instructions based on dry ounces, and as you have just pointed out: capfuls can and do vary hugely.
Enjoy your Envoy! Welcome to Spatopia.
