WTB: Reefkeeper Lite or Apex Controller

[DJYoshi]

I figured to get the Reefkeeper lite since it has everything that I could ask for.
Looking to control lights, auto top off, calcium reactor, have a standard ph probe for the tank as well, CA probe in the tank, possibly control the 4 power heads, and anything else that would help to automate. What kind of controller are you using? What are the pros/cons?

there's no CA probe. the RKL with SLI and an extra PC4 can do all that you have listed. Because I have one and it does all that.

Pros - Cheapest alternative to do all that you've listed.
Cons - I don't see any yet.
