Any thoughts on the pacific coast CL-650 chiller it is comparable to the prime brand from what I have read, and is about $50 cheaper. Does the pacific coast brand have the ability to plug in a heating element? I will buy one by this weekend. My tank got up to 87.5* today after we raised the thermostate in the house to save on electricity. Man, what a difference just three degrees in the house makes. I would hate to see what would happen if my A/C went out completely.
