    Muratic or Hydrochloric Acid

    Post split from another thread by SeanB - I think we were starting to confuse what should have been a relatively simple issue.

    Isn't it amazing to be able to separate fact from fantasy? Why wouldn't you be able to put Hydrochloric Acid in a pool, where it will release Chlorine ions into your water? Wouldn't 5 seconds of reflection tell you that it's probably the best acid to use in your pool BECAUSE it's hydrochloric acid?

    It's like the pool store guy telling me "Oh, you don't want to use bleach--it raises your total dissolved solids!" What is that dissolved solid it's adding? Salt! Sodium Chloride (Hey! More chlorine ions!) And if you use bleach for 5 years in your pool you still won't reach the salt levels needed for .....your salt-water generator! So....fact vs fiction.
    Stay ahead of your water!

    If I'm not mistaken, muriatic acid is hydrocloric acid.

    Yes, but in a different concentration. 31.5% is the muriatic concentration and it's what's generally referred to on the forum for pool use.

    (Yes, there are other concentrations but that discussion belongs in the "deep end". We are in "just getting started")

    Don't worry about it Carl, Just read the pool school section and you will soon learn that it only takes 5 minuts a day to stay ahead of your water!

    (One thing I have ALWAYS appreciated about Carl, besides his knowledge of pools, is is sense of humor! )

    Pools are hard work! I went out to test my water and check the pool last night, and I was out there for 45 minutes. Sure, for 43 minutes I was kicked back in my chair in the poolhouse with a beer listening to music , but I was keeping an eye on things, and I had to work pretty hard for 2 minutes testing my water, adding acid and switching my solar panels off BY HAND.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Ditto. I thought maybe I was missing something when he said his advice would be controversial....
    Thanks, guys., I felt funny contradicting FrustratedPoolMom, who wanted the OP to push CYA to 40 at the start.
    I'm a newbie here, y'know.
    No need, I'm still learning, and everybody has to figure what range works best for their pool, like a curve...hehehe you are absolutely welcome to contradict me anytime.....

    I guess most people don't realize that "Muriatic" acid is really a version of hydrochloric acid.
    Stay ahead of your water!

    Just about all pool stores sell muriatic acid. It's a standard pool chemical.
