Just wondering if anyone has made a DIY of the Avast Barrel Tender, which is also similar to JBJ ATO. Low level and high level float/pressure switch to control RODI unit. Someone else over here made one, but I don't know what 12v PCB he is using. http://www.chicagoreefs.com/forums/showthread.php/29845-Diy-rodi-refill-system
