How to cool the DWC buckets!

Title says it all, will start using water bottles tomorrow but I’m hoping for a more permanent solution without dishing out a huge amount of money any and all info and ideas HUGELY APPRECIATED

Frozen bottles or ice packs or a chiller.


I had same issue and I popped dwc top a little and added a fan on the ground for circulation. Pumps make heat and this is problem and having circulation fans low help.
