I wonder how this will hold up in my tank. I ordered some from CA to TX and it took 2-3 days in the worst heat wave to date here. I ordered a 4oz for a Reefer 250, so that's about 2:1 of what I need.
There is a blurb now on the bottle about "Although it is recommended to keep TurboStart refrigerated, it can withstand elevated temps for several days. Avoid extreme temperatures and keep refrigerated to ensure longest shelf life and viability."
I wonder if 110-120F temps qualify (maybe more, they sent via postal service)?
