What to check ?

[aswetich]

When you say check your "CL" frequently do you mean the "FC" ? What are the optium readings for the other stuff like ALK, Etc. (I have a liner pool)

Thanks

Yes - check your FC. Good readings for the other things:
Alk - 80-125
PH 7.4-7.6
Calcium - don't worry about it in a vinyl pool. (Unless it gets too high like over about 400 and then you may have a problem with cloudy water.)

Hope this helps.
