Home Depot Muriatic Acid

[RoyR]

Did I just make a mistake - instead of the Swimming Pool Muriatic Acid (14.5%) I got the other stuff, 31.45% - poured some in the pool - one box says Balance on it?

The HDX 1 Gal. Swimming Pool Muriatic Acid (2-Pack) is ready for use and does not require mixing. This pH reducer is designed to help prevent scaling caused by calcium-based chlorine and hard water.

Only difference is strength. The pool stuff fumes a bit less, but you have to use more double to get the same effect.

 

[wireform]

This is the better one to get. Cost the same as the half strength one. Make sure you adjust the pool math app for it.

I got my 2-;pack of MA from HD yesterday in their outdoor section. 31.5%.

Looks yellow in color right?

Looks yellow in color right?

Sometimes they do. I didn't really pay attention to this new batch, but now you have me curious. Ha.

 

[Desert Dog]

Yes it's yellow. I have a new box too.

I’ve used that one. Had to adjust the Baum in the Pool math app. That being said, that acid didn’t seem to have much of an effect on the pH when I’d add it. I had to add much more and still hardly got it to move. I clicked on this link expecting someone to say that certain batches were not very active .

Both boxes in the picture show 31.45% full strength acid.

Hold your breath when measuring and pouring.

 

[CraigChing]

Yeah, this is the one I use as well. As Oly said, hold your breath when pouring it, it is very noticeable if you inhale it. Pour slowly over a return, douse the bottle in the pool to avoid any getting on your decking, and just go slow.

NOTE: I personally don’t measure so that I avoid double handling and risking a spill. I simply eye-ball the level in the bottle. Just don’t inhale around the bottle when checking the level.

Seems like there are two products, one is called "adjuster" in a white box and a pool ball picture on it , the other "balance" in a brown box as shown in the post above. Both show the same 34% strength on the label.

Which one is better to get for pool use? Which one has a yellow color you guys are talking about?

We used that too. Make sure to add acid to water when diluting. Otherwise acid will splash and burn you

 

[Donldson]

Which one is better to get for pool use?

They are exactly the same.

 

[mknauss]

Make sure to add acid to water when diluting.

Do not dilute the acid. You are handling it twice. Pour directly from the jug into the pool water at the return with the pump running.

Thanks for the replies. In a previous thread on this forum I read that the yellow color might come from iron impurities. I would have guessed that the standards for drinking water and pool use would be higher than for cleaning and construction, but possibly its all the same.
