Balancing a pools pH with Boron in the water


Recommended Posts

Hi All,

One of the pH adjustment programs I use takes the amount of Boron in the water into account. I'm not sure it matters - So I'd like to know if the Boron concentration in pool water affects the amount of Hydrochloric Acid required.

If so, how? Is there a formula I can use to adjust for the amount of Boron?

Thanks in advance,

Buddy.

I don't know about a formula, but this link: https://www.borax.com/BoraxCorp/media/Borax-Main/Resources/Brochures/borates-swimming-pools.pdf seems to contain a lot of information about the use of borates in swimming pools. It seems to act as a buffer, enabling the chlorine to work in its best regime and also to soften the water by binding calcium.

If it acts as a buffer, it may be that by using borates you can fully control the pH with them alone and can dispense with the hydrochloric acid entirely, but I stress I am learning all this as I go in response to your queries, so you might want to do some further checking.

Thanks for the link exchemist

However I know what Boron is used for. I just don't know if the Boron levels affects the amount of Hydrochloric Acid I require.

OK, then I can't answer that for sure. But seeing as borate is sold as a buffering agent, it looks to me as if using it may make use of HCl unnecessary. But you would need to check with a supplier of borate, I guess.
