    I suspect a typo.

    I just googled it; wikipedia says it's very unstable, which in real terms means if it's 32% when bottled, it won't be anywhere close to that by the time you get it home.

    Hydrochloric acid is common.... also called Muriatic Acid. Typically sold at 31.45% for some reason unknown to me.
    16K freeform gunite with spa; Pentair 4000 DE filter; Century Whisperflow 1 HP; Pentair Minimax heater.
    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    I think that the reason is that acid was traditionally produced according to the Baumé scale, and that 20 Baumé is 31.45 %.
