    Best way to introduce Muriatic Acid?

    OK, I spent some time in Pool School and with the calculator, so I could safely lower my TA, which was 110 in my salt pool.

    The calculator says I should introduce 6.7 oz of MA. Then I saw some comments regarding the "slug" method and how it is a bad idea.

    How do you guys do it? Measure the acid, add to a bucket of water and pour into the pool? How far should I dilute?

    Or, with a small amount (less than 8 oz., say) is there any harm in adding directly to the pool and stirring to mix?

    Thanks, members of Trouble Free Pool, for being so friendly and informative!

    Just pour it slowly in front of a return with the pump running. Since your pool is fairly small, a good stir with a brush should take care of it.

    I do it the way 257 says. Just a note of caution - never add water to acid always add acid to water. So if you decide to dilute it and add it that way, put the water in the bucket first and then add the acid. You do want to be careful about splashes. I wear gloves, eye protection, and a respirator or a mask to avoid breathing the fumes or getting it on me in the event it splashes.

    Save a possible hazardous step and pour it straight in front of the return.

    Agree. The less you mess with it, the better IMHO.

    If you are going to add acid to water in a bucket, have the water in the bucket spinning when you add the acid and that will greatly reduce the risk of splashback. Pour the acid into the center depression caused by the circulating water.

    Thanks, everybody. Since I'd rather not mess with mixing, and then climbing the ladder with a heavy bucket to pour, I added the MA in front of the return as instructed. Easy peasy. Yes, I wear safety goggles and gloves. Wicked stuff.

    The main hazard with handling it is getting it in your eyes. Goggles are a good idea. Getting it on your skin for a sec doesn't hurt (unless you get it on a cut). Just rinse it off with water. What you don't want to do is spill it on something.

    >> I wear safety goggles and gloves. Wicked stuff.

    this was my primary reason for installing the Simpool automatic dosing system. about once every 2 weeks I insert a new bottle from home depot and don't have to smell or breathe any fumes as the system handles dosing and keeps pH steady at 7.4-7.6

    susa, that is very extreme to the point of being silly for a 3,500 gal above ground pool. For a small above ground pool just use dry acid if you don't feel comfortable with muriatic acid.

    I wear a mask too... one of those masks for TB, and it really helps a lot in not smelling those fumes and getting that full body repulsive reaction to smelling muriatic acid.

    I use MA to clean my Chlor-Ease, too. Hence the gloves, goggles (and apron).
