Laura,

Just sent your letter to a friend who is an electrical engineering genius. If he replies I will let you know his response.

> We have a group of students on campus that have designed a small aquaponics system.  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?
