Crazy. This whole thread turns out to be an "oops".I started this thread asking for Tropic Marine for help. Lou from TM suggested that I replicate my experience in another container and document it for Tropic Marin.
Guess what - I was NOT Able to replicate the residue building up on another container! Here are the pics when I mixed a fresh batch with TMP and three days later. Mixed clear and no residue.
