Hi all: I am fairly new to the hot tub I have (I bought the house with the tub already here). It is a 500 gallon, and I use Chlorine. The first time I started up the tub, I struggled with PH and Alkalinity. The second time, I used "Leisure Time pH Balance Plus" when I first filled it. for my 500 gallon tub, I used a full 3lb bottle per the instructions. For that fill, I had perfect PH and Alkalinity for the entire time until I drained it. Now I am trying to recreate it without the $20-$30 expense. The MSDS says that there are only 2 ingredients, baking soda and boric acid. Does anyone know what amounts to combine them in to recreate the mixture? Thanks a lot, Joel Also - does anyone use anything homemade to clean the pipes before draining the tub, like 'Leisure Time Jet Clean'?
