I think I have been trying too hard to keep the Ph at 7.5 so every other day when it hits 7.6 I add the 7oz of acid. Last week I wanted to see how high it would go left unadjusted. To my suprise it has remained stable at 7.6 and I haven't had to add any all week. I'll retest the Ch tonight at room temp. Thanks for your advice.
