You have however found a way that will not have any issues with salt water buildup and should run great. Good thinking with the mag. sensors.

I've been looking at doing something similar to my return, but i have a PLC on my tank, so should be much easier.

If you have a plc then you are correct, it is a no brainer as long as there are enough timers in the plc to give you all the random moves you require, a couple of units I have out there are programmed to change daily so that they actually match what is happening the same day in that part of the world where the corals came from, others are simply a real time repeat scenario, same thing every day with no tide influence.
If you ever have an questions feel free to email me, it is likely running somewhere, only to happy to help.

OM is a fun thing for me to do, I have many CNC's that produce product for large corporations which allows me to design build all I want, I couldn't program a plc if I tried, and at my age I have no intention in learning, I need more time on the golf course.
