Kh director & calcium reactor - settings

[francoisk]

Hi,

I have a kh director and separately a ph probe that manages the co2 in the reactors.

I read the manual and i understood what i have to do to manage the co2 in the reactors directly with the kh director.

I have some doubts on which value i have to set on:

1) Nom. Value change (ph)
2) limit for raise (ph)
3) limit for lower (ph)

At the moment i set on the ph probe a nominal value of 6.26 ph, hysteresis 0.05 ph and i have in the tank a kh of 7.

Id like to know which value i have to set for 1), 2), 3) with a kh nominal value of 7 for a directly manage of the kh director to the co2 erogation: i'd like to reduce as minimum as possible the kh variation.

ty for your support
