Neat observation about my new system and reactor

[Doug]

Jon,
I found that a good effluent flow rate, with say a specific co2 rate, produces an effluent with an alk of around 30dkh and a calcium of mid to low 400ppm. Thats means it can just maintain normal levels, which is what most of us have noticed.

However, in a thread many moons ago, Stephane mentioned that he noticed by keeping the same bbm and reducing the effluent rate slightly, the calcium output increased and the alk decreased.

Thats what I am trying to achieve. Now if I would just quit moving my reactor, I could find out.
