Will higher dKH in non-CO2 tank result in more dissolved CO2?
I have a successful High Tech tank, I'm hooked on the hobby, and now want to set up my first Low Tech NON-CO2 tank, just to try it. I'm trying to decide on where I will set my water parameters, specifically dKH. I do have options on water, i.e. city, softened(w/potassium salt) , and RO. A 50/50 mix of City and RO water gives me a dKH of just 2, same Gh, and a PH of 6.8. A dKH of 2 seems low to me (Im a former Reef guy) but I have read 2 is okay, BUT..
In looking at the Kh/Ph/CO2 tables, I can achieve higher CO2 levels with a higher dKH.
Is achieving higher CO2 in my low tech non CO2 tank as simple as running it with a higher dKH? is it that simple or am I missing something? I appreciate the advise , Thanks
