Soda Ash For Increasing Swimming Pool pH Level

by Stan

My Intex 15" swimming pool pH level is low, around 6.2.


Can I use soda ash to increase the pH level for Intex frame pool?




Thanks for your question Stan

Yes you can use soda ash as a pH increaser.

Some people like to use sodium Bicarbonate as well, but this does affect the total alkalinity a bit more than soda ash, but both are very good as a pH increase.

Ways Of Lowering Pool Total Alkalinity..Maintain pH Level

by Rob
(Billings, Montana)

Currently, my pool has slightly elevated pH levels (about 7.8, so not out of range--but could be slightly lower). My total alkalinity, however, was off the charts--at 280. Now it is 210. My problem, of course, is that while acid lowers the Alkalinity and pH levels, in order to bring pH back up to the 7.5-7.6 range, I need soda ash, which also increases the total alkalinity?

My guess is a back and forth game that will slowly bring my total alkalinity level down, while balancing my swimming pool pH level.

Any specific suggestions?

Thanks for your question Rob

This is an issue that many pool owners have; raising or lowering the pool pH level or total alkalinity while not doing something to the other side.

You can use these link to help in your situation:

Swimming Pool Alkalinity..Adjusting Your Pool Chemistry

Swimming Pool pH Levels

To lower the pool total alkalinity you'll want to used muriatic acid and keep the pump motor off.

To lower the swimming pool pH levels use acid but turn on the pump motor along with any water features you might have; slides, water fountains, etc...

You also can use 20 Mule Team Borax or Sodium Bicarbonate, baking soda, to increase the pH level without much happening to the alkalinity.

Just use the above links and you'll be fine. You'll also find a chart for how much muriatic acid you need to decrease both the pool pH level and total alkalinity.

Water pH in Pool

by Anni
(Mid France,Charentes)

My ph reading is around 7.8 - 8.2. I do not know if I need to add pH plus or pH minus. When it says: Add acid, what do I add?

My pool goes green very easily. One day it is clear and the next day the green is coming back.




Thanks for the question Anni

To lower your pH level you'll use pool acid. The most common and effective is muriatic acid.

Sodium bicarbonate (regular baking soda) or 20 Mule Team Borax can be used to raise the pH.

Your chlorine is much less effective at a pH over 8.0ppm. This could be part of the problem with your pool going green.

I'd like to have your complete chemical readings:

Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, and Metals (iron and copper). It makes troubleshooting much easier. You can get this done at your local pool store.

It would also help to know the size and type of pool you have. Plaster, vinyl, fiberglass, etc...

If you can get back to me with the chemical numbers and I'm sure I can help clear up your pool and keep the problems from happening again.

Pool pH level

by Charlie S.
(Mesa, AZ)

I have a comment about my pool pH level.

Everyone always told me to have the pH level of my pool at 7.2. That's before I found this website. On the pH page it says to keep my pH level between 7.6-7.8.

I thought I might try it and boy did it work.

I never realized just how much acid I was using to keep my pH at 7.2.

After I would have a pool party I wondered why the level was up that high, but now I know.

My chlorine level still fine and everything else is in check. My pool pH level is great.

I wanted to thank Robert for all of the great info. on his site.

It has already saved me money and I know it will save me even more next Summer because now I know what to do.
