It seems like tons of guys have issues with root rot from high water temps. It also seems like power consumption is sometimes an issue after you factor in lights, a/c and pumps, not to mention an added chiller. Is it feasible to use ice chests in a dwc setup instead of buckets? I figure that this should keep the water temps from being effected so drastically from the room temps. What about using a cooler for the res? Has anyone seen this, done this or have pics of this?
