Clorox pH down

[lindz18]

I searched the forums and could not find a close post to answer my question:

Can I use Clorox pH down to lower my pH? It is consistently showing 8.0 so I feel I need to lower it a tad. It says it is sodium bisulfate.

Thanks

We do not recommend the use of Dry Acid aka Sodium Bisulfate. The sulfates build up in the water and can damage metals and concrete.

Recommended Pool Chemicals

Which should I buy? TFP's recommended pool chemicals are cheap, easy, and won't unbalance your pool water.

That is just a fancy name for Dry Acid, Poolmath can give you the dose.

Since you own it, use it, but don't buy any more. It leaves sulfites behind which you don't want.

Thank you!!! What does the sulfate do? Does me having a vinyl liner help? I will use this one time, but will not use in the future. Thanks for letting me know and for the help as usual! You have helped me since day 1 through my CYA over 200 catastrophe from an inherited pool!

What would you recommend for my first chemical add? I don't want to take it too low! It says 28 ozs by volume to get it from 8 to7.5. My TA is 60.

Do not lower your pH below 7.6. So use ~20 oz of the dry acid.

7.5 is a good target. If you miscalculated the pool volume, you've got plenty f wiggle room on either side.

Sulfites can damage saltwater chlorine generators and concrete. Your vinyl pool is in your favor. For me, I just don't like the idea of adding sulfur in any form. What conditions could cause it to start smelling? I don't know, and I don't wish to find out.

I plan to use dry acid when/if I ever need to, because my hands shake something awful and I'm afraid of dumping muriatic acid all over the place. Especially as strong as it is for pools.

So dry acid does have its uses.
