The average kH for my tank has been 8 – 9 dKH for the last few months. I have an auto top off of kalk and 24/7 dosing of ESV B-Ionic two part via Litermeter III. A couple days ago, I dialed down the level of 2 part that is dosed daily. Tested kH for the 1st time in 4 days today, and it’s ~7, which is what I’m shooting for. I’ll start testing daily and adjusting the two part dose accordingly till the tank is steadily in the 7-8 dKH range, as close to 7 – 7.5 as possible.
