Muriatic Acid Vs "Green" Muriatic Acid

[1poolguy]

I went to Lowes's to buy Muriatic Acid and they sell both "Green" and regular Muriatic Acid. They were out of the regular which is all that I have been using so I bought some of the "Green" and used it in my pool. What is the difference and which one is better for a pool. I like the low fume of the "Green".

The Green is normally about half strength. So you can use it, be sure to adjust to the right strength in PoolMath. It costs about twice per effective amount of acid, but up to you.

Thanks for the reply. The "Green" bottle did not list the concentration but I thought it must be diluted because it is taking much more to bring down the PH.

Google the brand. They have to have a MSDS for the product. It will state its concentration. Normally 20% or 14.5% vs the full strength 31.45%

Yep. I just discovered this myself. Headed back to the home store to exchange "green" for regular. It's the same price, but no details on the label. Live and learn. Plus, there is no 20% option in Pool Math, so using this would feel like a step backward toward the guessing game.

I think it's the 14.5% strength

Just for kicks, if 31% is full strength, then my 36% must be turbo strength.......

Yep. The MSDS for the straight Jasco MA says 31-35%. I guess once you get up around 20 Baume, you're on your own. PPE, baby.
