How do you "control" your reef tank?

[kien]

I control my reef with a Profilux controller. I don't have any experience with any other controller so I can't really comment on the others, except maybe to say that they are all pretty much on par in terms of features. Can't really go wrong with any of the commercial ones on the market.

Here's what my profilux does for me:

* Controls all lights (daylights, sunrise, sunset, moon lights, lightening storms)
* Monitors and controls temperature. Temp too low, turn on thermometer, temp too high, turn off thermometer, turn on fan. No more stuck heaters!
* Monitors pH, Salinity, ORP.
* Performs Automatic Water Top off and Salinity control. If more water is needed and the salinity is a bit low, pump water in from saltwater mix, if salinity is okay, pump water in from fresh water storage.
* Daily email reports on all monitored parameters and settings (lights, etc).
* emailed alarms if a parameter is out of whack
* Tunze powerhead control (up to 4). No need to buy a separate tunze powerhead controller. Allows you to run the tunze powerheads any which way you like (constant, random, reef crest, etc).
* controls doser to maintain stable Alkalinity and Calcium.
* iPhone native app coming soon!

* I am right in the process of setting up an automatic water change utilizing a couple of float switches with the profilux

Again, I have no experience with the other controllers but I sure do love my Profilux
