I would say your gonna want a controller of some sort to control lights.heater.dosers.fans.pumps..etc....and monitor pH and temp.....apex or reef keeper
And for testing I like salifert to test alkalinity.calcium.pH.nitrate.phosphates.and magnesium...
You can swing by and check out some stuff sometime.....
Can you log pH swings with the reef keeper elite. I see you guys doing it with the Neptune apex
Don't hold me to it but I believe Reeftronics.net will log Reefkeeper data too. The big benefit is if reeftronics is unable to communicate with your controller for one hour, they will send you a text message. This is beneficial because you may be experiencing a power outage and it would alert you to get home and rectify the problem. Much cheaper than going the extra energy bar and ups route.
