I was just reading the "Water Balance for SWG" once again and got to the pH recommendation of 7.5-7.6 - stating that this was important. I have been running the SWG since the middle of June and I added borates in the middle of June. Ever since my pH has been steady at 7.2-7.5 - usually closer to 7.2. I have not wanted to add to bring it up since my TA is already back in the 80-90 range (it rose back up after adding borates). I have not added any acid since I added the borates.
Do I need to raise my pH to 7.5? or since it has been steady, can I just leave it at 7.2?
