I'm building a 110 reef and have an Apex. Would you mind giving me a recomendation for a cacium reactor and ATO that would interface with the Apex?

I'm still pretty new to this...but, alas, I'm hooked.

Thanks so much!

There is no special interface per se. You would control them much the same as you would a heater. In the case of the calcium reactor, it is typical to monitor the internal pH or the effluent. Then you can control either the CO2 solenoid or the feed pump via an outlet, it depends on the particular design. The Apex is fully capable of performing ATO, you would not need a seperate controller. Basically, you would need a Breakout Box and a few float switches. By monitoring the switches, you would again control either a pump or solenoid via an outlet.

If you have not already read it, the New Users Guide stickied at the top of the forum is an excellent resource.
