Hi Waterbear.
I'm new here. I was searching online for info on cleaning a hot tub and lines with vinegar. I was searching for info- since vinegar is acidic, do you maintain water chemistry when doing this 3 week vinegar cleanse? Then I stumbled onto this forum, and initially became very confused. I have been trying to locate your 2 and 3 step bromin process, and to understand the spa water chemistry better. I have experienced some water conditions listed throughout the forum in my spa and inground pool at one time or another. Could you direct me to where I can locate this information, as well as decontaminating my hot tub. I recently purchased this house, and the tub was included in the sale. Thank you!
