Adding Borate, why muriatic acid ?

[YoRgH]

Hello,

I decided adding borate to my pool, but why adding muriatic acid? Why not sodium bisulfate?

Muriatic acid is hard to find in my region...

Thanks !

Yes, you can use it. Muriatic acid is usually cheaper to use. Check the paint and hardware stores?

Hello,
I finally found muriatic acid, but it' sur not cheaper here.....

For my 45 000 liters pool, for each add of 2 kg of borate, i must add 1 liter muriatic acid, or 1,2 kg dry acid.

Dry acid cost 8$ for 3 kg
Muriatic acid cost 6,50$ for 1 liter

Muriatic is more than 2x expensive here.....

Bye

That's unfortunate. Muriatic has less side effect, meaning dry Acid adds Sulfates. Undesirable because it can add to scaling with Calcium Sulfate type scaling, and although unusual, it can come out of solution and crystalize. There was recently a post about just this thing happening. Maybe it's a Canadian thing, but MA is plentiful here, and cheaper than dry acid when you run the numbers on it for a source of pH control.

Boric acid pellets from Duda Diesal is the way to go if you could have gotten it. Don't need to deal with the muriatic acid after adding.

You don't need to use mutriatic acid if you add the borates via boric acid rather than via borates.

Maybe Duda Diesel ship to Canada?
