I am going to stick w/ my current IC and make a second IC that I will have sitting in an ice bath to cool down the water going to the wort chiller.
I tried this first and found the second IC chiller really decreased the flowrate and didnt really cool the water all that much. Plus its still wasting a lot of water.
Buying the Pond Pump at lowes along with the hose and hose fittings was cheaper than buying another IC. I traded my two 3/8" ID ICs in for one homemade 1/2" IC. That also helped a lot.
Thanks for sharing your experience w/ the second IC!
