Muriatic acids vs hydrochloric acid?

[leeovery]

Hi

I just received my order of muriatic acid and its labelled as hydrochloric acid. I know they are essentially the same thing, with muriatic having high baume rating due to impurities, but can I safely use hydrochloric in my hot tub to lower ph/ta?

My ta is very high hence why I ordered the liquid acid. Using dry acid is costing a fortune.

This hydrochloric acid is labelled as "Hydrochloric Acid 36". I assume the 36 means 36%. The PoolMath calculator doesn't go up to this strength. Is this safe to use?

Thanks
Lee

Yes exactly the same
My hydrochloric acid is 36% and I use 34.6%
Not a lot of difference and you can always put in a bit less
Be careful as it lowers pH as well, best to concentrate on lowering pH and then aerating to raise the pH until you have the right numbers

Baume has nothing to do with impurites. It is an archaic system of referring to density or specific gravity.

For that matter, Muriatic Acid is an archaic term for Hydrochloric Acid.

Ok thanks to you both. Appreciate it.
