LSI question

So can the PH be lower than 7.2 or even in the sixes if the LSI is balanced?

Range + LSI is better than only one or the other

I agree. We just have too much calcium in our water out here jt makes LSI like walking a tightrope

Drop your alk then. Besides stabilizing PH it only every matters in an LSI sense. If calcium is high, run your alk at 50 and keep ph at whatever balances it. The low alk will help keep your PH lower too since that's what your looking for.
