Dono, how do you plan to temper and acclimate the fish at your supplier to YOUR pond water at HIS place? Seriously, for a 20 minute haul, only TWO things are needed...enough water for the pounds of fish hauled (about 2 gallons per pound of fish or 18 liter per kg) and water movement with air or a small water pump. Adding salt, ice. your own water at the supplier's site or any chemical will cause you far more problems than solutions in such a short ride!
In fact, if you have twice the water to fish weight, you won't even need air for a haul that short!! KISS applies here
