Assuming my Ca reactor is well tuned (1 bubble per 4-5 secs, effluent drip of about once every 4 secs), will kH fluctuate during the day and night?
About 3-4 days ago measured my kH. Was around 8.4. Had nothing to do just now so I checked my kH. It was around 7.6.
Calcium level did'nt change, around 430ppm.
What should I do? Is my effluent drip too slow? Or should I buffer up my kH with sodium bicarbonate?
Oh yes, only recently started to dose kalkwasser at night. Could this have brought down the kH somehow?
