Soda Ash Pool Ph

Soda ash has a high ph somewhere between 11 3 11 7.

Soda ash pool ph. If the ph is low but the alkalinity is in the proper range use soda ash to raise the ph. This massive difference in ph is why we recommend neutralizing acid washes with soda ash not bicarb. Sodium carbonate na2co3 more commonly known as soda ash is an additive to raise the ph and alkalinity in swimming pools. The active ingredient in our ph increaser is soda ash aka sodium carbonate.

Sodium carbonate soda ash is the most common chemical used to raise ph and total alkalinity in pools. Use chemical reagents or test strips to find the current ph. In fact it is the latter that has become common practice often supported by the argument that sodium carbonate is more likely to cloud the water. If the pool has a fountain or water feature it can be run to raise the pool water ph.

Corrects acidic water conditions by raising water ph levels slows the rapid dissipation of chlorine caused by acidic water. Test the water for ph and total alkalinity using test strips or a pool test kit. Aerating the water will also raise ph in pool water. Although they both raise ph baking soda has a stronger effect on total alkalinity than soda ash.

And soda ash sodium carbonate is used to raise ph and slightly raises alkalinity. To raise ph in pool use washing soda dosa ash or borax. Raises ph quickly to correct acidic pool water. And that s way too much.

This would also increase the total alkalinity by roughly 150 ppm parts per million. For example let s say the ph in your pool measured 7 0 and you have a 20 000 gallon pool. Add baking soda if the ph is below 7 2 and the total alkalinity is below 80 ppm. Those of you reading this who have used soda ash may have had it cloud up a pool.

For example getting a ph reading around 7 2 to 7 6 in 10 000 gallons 37 854 liters of pool water would take roughly 21 pounds of baking soda. Let s look at the ph scale below. Figure out how much soda ash you need. For example you test the ph of the water and it shows 7 2.

Use about six ounces 170 g of soda ash to raise 10 000 gallons 37854 liters of water by 2 ph points. Soda ash is approximately 1000 1200 times more basic than sodium bicarb. The ph difference between them is substantial. Start with this figure as a guide and add more soda ash later if you need to raise the ph by more.
