Hi David
I have a 320 liter tank. I add about 300 to 400ml of Kalk through a stirrer and I get a peak pH of 8.74 during the day. Frustratingly I am not sure if I believe the Apex pH probe, although it does calibrate. Most people it seems struggle to get their pH above a certain point, I seem to have the opposite problem!
