How do you add muriatic acid?

[cwstnsko]

I always pour my acid into a measuring cup before adding it to the pool, otherwise I always seem to overdose. I normally spread mine around over the deepest section of the pool with my pump on high speed. As others have said, watch the wind direction, the fumes are nasty, be careful not to splash it on yourself or anything else, and rinse immediately if you do

To avoid spilling the acid, I mark the gallon jug at one pint increments. I calibrated a paint stick with markings for each pint using an empty jug and water. That way I know how much I am adding without having to use a measuring cup.

I add it slowly in an arc around the return but fumes never seem to be an issue for me.

Well I went ahead and used the acid. It scared the beegeezees out of me when the white smoke vapors started coming out from under the cap when opening. I'll see what the ph is in a little while. Using a measuring cup sound interesting because I was only guessing with the amount. Denise

That is all I ever do is guess, I have gotten pretty good at it too. But I am heading to Walmart here after a while for another batch of bleach so I may pick up a measuring cup and I would like to start keeping track of things. The MA scares me too, especially now with one eye, I am healing with the other one, but I tell you not having one is aweful, and not having any would be unbearable, protect your eyes at all costs. This stuff is Hydrochloric Acid, very potent stuff.

I put my plastic measuring cup on a plastic cafeteria type tray so if I spill any I can just throw the whole tray right into the pool. (with an inground pool it's easy...just push it in.)

I've never pre-mixed or diluted the acid simply because I feel like I'd be handling it one extra time and thus one more chance for a spill or splash. I don't know if it's been mentioned yet but I always open the jug outside next to the pool rather than inside the garage where I store it. Again: fumes, spills and splashes inside the garage--that would be bad.

Plus, acid washed jeans aren't cool anymore!

When I first started using M. Acid it was if I were going into space. I had so much protection on I had a difficult time moving. It took me 30 minutes to add one cup of the stuff. As time went by I began to wear less and less stuff. So one day after church I remembered that I needed to add a cup (you guys no were I'm going with this) So instead of changing first I went out grabbbed the jug and started pouring in the deep end. Replaced the cap and went inside, seconds later my wife screamed at me was I alright , I looked at her and asked what she was talking about. She pointed to my pants and all I could do was stand there in amazement. Without my knowing the acid had splashed up my pant legs and totally ruined my slacks. Let's just say my new nickname is Neil Armstrong.
