Tank controller, doser, and kalk reactor build

So, I've been teaching a lot or had projects and a lot of stuff has been sitting around...

This is exemplified by the recent SOS installation...not sure how long I had it before I installed it...stupid me found out it was simple to install.

Anyway, what I have sitting around are -
Apex standard controller base unit
Energy bar
Apex display
PH and temp probes
ioGear WIFI connector...don't want to run an ethernet cable across my office
eshopps IV-2000 Master dosing pump
Two little fishies Kalk reactor

I've been thinking on where to start...the Apex seems the logical choice given I'll run stuff through it's energy bar. Also setup the display and probes.

Followed by the wifi connector so I can remotely access it.

Then the dosing pump...gotta some how hook up the Kalk reactor and the ATO reservoir? This is where I'd appreciate some input...

I've thought of using a small pump I have placed in the reservoir connected to the doser and the doser to the sump...but do I need to control the pump into the reactor from the ATO reservoir? I presume I don't want it running all the time...

So, want to help me jazz up my system? :thumbup: :help:
