After setting the main clock, you can set the LCD backlight brightness. This brightness is dimmed down to after 5 seconds of being on the main screen. The LCD will be visible on the outside of my tank stand, so this is needed to keep it from being full brightness all the time.
From there, we can turn on/off all the components independently:
And so on for the CO2, filter, and heater. Next is setting up the dosing pumps.
If you noticed, I have 3 pumps but only the micro and Macro ferts setup on the main screen. I have the 3rd pump setup so that if I keep it at 0 second on time, it just gets skipped over. But if I decide I need it at some point, be it for adding glut or iron or whatever, I can set the timer >0sec and it will dose along with the first two.
After setting the pump speeds and times (which I will use to calibrate the pumps to inject a certain amount of fert...) I will then set how much fert I just calibrated the pumps to. I wanted to keep the freedom of being able to decide later down the road to maybe inject 10mL of fert at a time, or maybe 5mL will be enough. I will be mixing up my liquid ferts using dry powders, so I will have a lot of flexibility. I'm currently thinking of dosing 10mL per dose, and having 500mL bottles. That sets me up for 50 doses, every other day, which means they'll last like 4 months. That may be too long... I dunno
And finally the size of the bottles I'll be filling. Again, I don't know if 500mL bottles will be what I finally decide on. I have this to be set between 100mL and 2000mL. That should cover me.
