I've been looking around and have had a hard time trying to figure out what is the best levels for an AGP in reguards to calcium hardness. I realize this is not as important with having a vinyl liner, however I want to make sure I'm still within an acceptable range. Any help would be greatly appreciated.

Thank you,
