i hear alot about a tanks parameters and in particular calcium, alkalinity, and magnesium and i've been referred to several calculators for achieving the desired levels of those 3 areas of your tank, the big problem was finding my currant levels.
i just bought an aquacontroller 3 after setting it up i get this

temp: 77.4
ph: 7.79
ORP: 484mv


1st i don't know if these are even correct, but where are the levels of cal, alk, mag? is the AC3 the wrong device??
does ph, orp tell me anything about cal, alk, mag?

thanks, joel
