What do you mean by needle valve? Also, are you not running a cal reactor anymore? Why?Originally Posted by iggy
The unit I'm getting is a KNOP package #2. I'm getting it at 300$ which I feel is very high for used equipment, but I want to get on this guys good side for a future custom build. Do you know anything about KNOP reactors?
As a decent doser will run almost as much as cal reactor, I wanted to try combining the iron dosing bit with the Ca/Alk. Is it feasible to add iron to the reactor media chamber?
I want to maintain a 8.4 pH, but don't want to have to dose anything, thus the Ca reactor, is it possible with a strong scrubber to maintain high pH when running a Ca reactor? Or is kalk an inevitability?
