Low pH and Ammonium
I dose liquid ferts, inject CO2, and have a fairly heavily planted tank.
My degassed pH is 6.5, and I am lowering the pH with the CO2 presently to about 5.9. The nearly worthless dropchecker is always green, never gotten close to yellow.
TDS about 200
I currently have to CO2 come on about an hour before the lights come on, with a 6-1/2 hr photoperiod, shutting off when the lights go off. I do this to save CO2, and allow the pH to climb to allow the BB the ability to process the NH3 at the higher pH when the lights are off, as they wont do much with the NH4 with the low pH for about 7 hours per day.
Would it be best to simply run the CO2 all the time and not stress my shrimp and fish?
