Thanks for the replies, I dosed 20ml of each part yesterday, I will test later today and see if I need add more...
Having 4 clams, I think that is the source of my CA going down
I'll get the hang of this dosing thing sooner or later
I have superbuffer dKH and Kalwasser as well, I figured the Tech CB would be easier to dose until I get used to this kinda thing (never dosed a thing before)
