You may consider doing a bit of reading... if you don't know what a chiller is, you could definitely benefit.
My point is... there are gonna be plenty of questions you will want answers too... read!

a reservoir chiller keeps the reservoir water from heating up to an undesirable temp

put your bucket into another bigger bucket of cold water... or just try the bigger bucket.. good luck.......
