I am converting my neighbor to the BBB method after I tested their pool and they found the true results of their water and not the pool store results So here are their numbers:
pH-6.3ish (Did base demand test and it took 55 drops of reagnet to get the pH to 7.0 )
They have an 27'AG with a volume of 18,500 gallons with a vinyl liner. They currently use Trichlor 3" tablets with an in-line feeder. I want to make sure I get them going in the right direction. I have told them the pH is the most important and to start adding Borax to raise it up, then we will start working on the TA. Is this the way to proceed?
