I've been thinking about adding a CR to my 125. Here's my question:
Since a CR is supposed to <u>maintain </u>calcium and alkalinity at specified levels -- (I've read that using a CR to raise these parms is not the idea -- maintain is the objective) what happens when you do a WC -- does the CR have to be adjusted to raise those parms to the desired level? i.e. does the <u>new </u>water usually have parms that are lower than the target set for the CR?
I've read a number of posts here about the parms of certain salts. Some seem to have higher parms than others from the start. IF newly mixed salt water has the parms desired -- would weekly 10 to 20% water changes accomplish the same thing as a CR -- in the long run?
