I've read through some threads covering the topic of recirculating pumps for ICs but no one seems to say what they would think would be an ideal rate of flow. I want to setup the pump in a cooler with ice water and recirculate through my IC. I've heard some say that too slow or too fast could reduce your chilling rate. I have no idea how to come up with the ideal rate. I have a 3/8" 25' stainless IC. I've been just hooking up the water hose but it is starting to warm up here in Houston.
