Recommended Calcium Hardness Levels

[KevJB]

Thanks for the advice! I'll try all of this!

I'd still like to be able to set custom ranges in the app for my sanity.

I went through this with my Pebbletec pool. In particular, Calcium Hardness. TFP recommends 350-550 and Pebbletec recommends 150-250 In their maintenance procedures. So I called Ptec (800-937-5058) and they stated if I didn’t maintain the 150-250 range it would void my warranty.
I have too much investment in this new pool to jeopardize my warranty. Bottom line, if you have a Ptec warranty, do what they say.
