[Sc-aquaponics] [Aqua-ohio] Question of the day

[Lance Lyons]

Laura I think a couple of zero speed switches connected to the motor shafts would work fine. I can pick up an auto Dailer in Huntington for about 35.00 dollars. If the Doctor releases me too drive I can come out next week and hook it up for them no problem

The water quality is very stable, and they would like to reduce their time commitment by not feeding or monitoring water quality on the weekends.  They realize the risk, and want to look into some kind of “alarm” system.  Here at Piketon, we use phone dialers with sensors on the water pumps and airlines, but this is too expensive for them (around $600.00).  They are not using supplemental oxygen, so they would like to monitor water flow from the pump, is it on or off.  Any ideas as to how to do this inexpensively?
