Well the cool box of water did not work to keep the fermentation temperatures in check so a new plan was needed. Using a pub flash cooler to pump cool water around the fermentation cooling coil seemed to be the best plan. After waiting on Ebay and gumtree we finally found a unit at the right price. After a 30 minute change to the fermentation control box and we where up and running with far superior cooling power even for the hottest of days. We could even cold crash the beer down to 2 degrees.
