Thanks for the input people. Im sure running the chiller at like 60 would sufice to bringing all 6 buckets in the low 60's range. Im actually lowering the chillers input pump from 360 to a 185gph considering my res/controller bucket is a mere 5 gallons, not the 40 gallon res i had it dialed to for the previous system.

But heres what im wondering. A while ago when I last ran a Recirculating DWC, i used a pump in the controller that pumped water up through a 1/4" line splitter that split into 6 1/4" lines. Each line ran to each of the 6 buckets lids, so the recirculating system pumped from the controller, through the lines to all 6 buckets, and flowed back through the 1/2" tubing that connected all the buckets to the controller. (same as the recirc. dwc that was explained on a OG how to)

Now, I want to make the recirculation tubing different. As in, instead of the 6 line splitter, I want to run it through 2 lines of 1/2" tubing, that connect 3 buckets on each line, so the the buckets would all be inline. I think this would work a little more efficent what do you all think. Thanks. :smokin:
