Soda Ash Pool Ph

Use chemical reagents or test strips to find the current ph.

Soda ash pool ph.

Let s look at the ph scale below. Those of you reading this who have used soda ash may have had it cloud up a pool. Use about six ounces 170 g of soda ash to raise 10 000 gallons 37854 liters of water by 2 ph points. For example let s say the ph in your pool measured 7 0 and you have a 20 000 gallon pool.

This massive difference in ph is why we recommend neutralizing acid washes with soda ash not bicarb. And that s way too much. Although they both raise ph baking soda has a stronger effect on total alkalinity than soda ash. It takes about 6 ounces for every 2 ph points you need to raise 10 000 gallons of water.

This would also increase the total alkalinity by roughly 150 ppm parts per million. The active ingredient in our ph increaser is soda ash aka sodium carbonate. Aerating the water will also raise ph in pool water. Soda ash is approximately 1000 1200 times more basic than sodium bicarb.

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. 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. The ph difference between them is substantial. Sodium carbonate na2co3 more commonly known as soda ash is an additive to raise the ph and alkalinity in swimming pools.

Figure out how much soda ash you need. Corrects acidic water conditions by raising water ph levels slows the rapid dissipation of chlorine caused by acidic water. Start with this figure as a guide and add more soda ash later if you need to raise the ph by more. For example you test the ph of the water and it shows 7 2.

Soda ash has a high ph somewhere between 11 3 11 7. Test the water for ph and total alkalinity using test strips or a pool test kit. So if very few service companies are purchasing soda ash one can extrapolate that either the ph in swimming pool water is never low or individuals are using sodium baking soda to adjust ph. Raises ph quickly to correct acidic pool water.

Total alkalinity is a measure of the ability of the water to maintain a stable ph and it should be between 80 and 120 parts per million. And soda ash sodium carbonate is used to raise ph and slightly raises alkalinity. If the pool has a fountain or water feature it can be run to raise the pool water ph. Add baking soda if the ph is below 7 2 and the total alkalinity is below 80 ppm.
