The DIY stone seemed to work good, no leaks and was pumping oxygen. As for the 125' of 6/3, my run to the main panel was with rough measuring, 90-95'. I did pretty much the whole building myself and trying to measure 100% accurate for the wire by myself just wouldn't have happened. I'd rather have extra and either keep it for future use or sell it rather then come up short. For the springs, i will try to get you the link for them sometime at work today. Now on to my results. Most eveyhing worked great. The vent fan cut out on me part way through. It has an overheat protect switch on it and apparently running it half throttle heats it up pretty good. I may end up having to get an inline fan anyway now. Also, the chiller didn't cool to fermentation temps in one pass like i was hoping. The pid readout (which worked awesome by the way!) On a single pass was about 95 degrees. Circulated back into the kettle and brought the whole volume down to about 130 then ran it through and got a steady 63-64 degrees into the fermented.
