I found photos from my reactor setup and Pro controller on the desktop.
As you can see LCD screen is very simply - you can increase/decrease flow thru pump(it's step motor pump) and you can see status of optical sensor/solenoid valve.
If your corals start growing and calcium / alkalinity levels will drop, you simply need to increase flow on dosing pump.
Of course, it have several protections like empty CO2 bottle alarm(sound alarm also), you can perform a software update by built-in USB port(app is actually available on Mac OS and Windows).
I think that using calcium rector(a specially that CalcFeeder PRO) is one of easiest methods supplementing tank with Calcium and keeping stable alkalinity levels..
There is no pH probe , so not needed calibration every few months, no needed pH computer/controller etc.
You are getting ready to use set - only CO2 bottle and regulator(we suggest not buying cheapest ones - they usually don't keep stable pressure on output) - is everything what you need.
