If you have them cranked they will yes. I have seen it too. But then you have to readjust and dial it back or have fun with chasing numbers all over again. ;)

I like having the tank at the numbers I like and dialing the reactor in from there. :) less work. ;) And less work is good.

but that's my .02 :D

how often do you start a tank with 450Ca and 13alk?
