I finally took the borate plunge. I used TFP's guidelines on adding 20MTB and acid. Using TFP's recommended Lamotte test strips, my borate tested at 50. I was shooting for 40...not sure how that happened. Prior to borates I was adding acid every other day to keep PH around 7.4. I was adding 8-12 ounces of MA every other day. Using TFP's recommendations, I'm now using 7.5 as the standard for my pool type. My spa to pool water feature runs strong (est. 3/4 open) for 8 hours a day. Using the smart phone PC recommendation, I'm adding MA every other day (25 ounces) to reduce PH 7.8 to 7.5 with borates at 50 and TA at 75. Seems like I've doubled my acid use since adding borates. According to TFP, TA can run 60-80, so I picked 70-75 as a midpoint. Should I drop my TA to 70 or lower to reduce MA consumption? Any other suggestions?
