I guess some PPL know i have NO3 , PH,KH, Ca and MG problem.
I been searching why my parameter fluctuate .
Recently i bought sulphur DeNitrator, after few week, i collect some drop of water from sulphur DeNitrator
Result :
KH = 1 (from sulphur DeNitrator)
NO3 = 5 PPM
KH = 6 (tank)
NO3 = 50 PPM (tank, used to be 100 PPM)
Hope i am correct.
My CA and MG fluctuate due to KH too low, am i collect?
