Soda Ash Substitutes for Pool pH

Discover the best soda ash substitutes for pool maintenance including washing soda, baking soda, and pH increaser products for proper pool water balance.

Quick Answer

The best soda ash substitute for pool pH adjustment is washing soda (sodium carbonate) at a 1:1 ratio, or commercial pH increaser products. Baking soda can work but is less effective for raising pH.

Best Substitutes

Washing Soda (Sodium Carbonate)

1:1

Washing soda is chemically identical to soda ash and provides the same pH-raising effect for pool water. It's the most reliable substitute for pool maintenance.

Best for:

pool pH adjustmentraising total alkalinityswimming pool maintenancehot tub maintenance

Identical to soda ash - most effective substitute for pool pH adjustment

Commercial pH Increaser

Follow product instructions

Commercial pH increaser products are specifically formulated for pool use and often contain sodium carbonate or similar compounds. Follow manufacturer instructions for proper dosing.

Best for:

pool maintenancewhen convenience is priorityprofessional pool care

Designed specifically for pools - most convenient option

Baking Soda (Sodium Bicarbonate)

2:1 (baking soda to soda ash)

Baking soda will raise pH slightly but is more effective for raising total alkalinity. Use twice the amount of soda ash for similar pH effect.

Best for:

alkalinity adjustmentwhen pH is only slightly lowemergency situations

Less effective for pH - better for alkalinity adjustment

Sodium Hydroxide (Lye)

0.5:1 (half the amount of soda ash)

Lye is much stronger than soda ash and should only be used by experienced professionals. Use half the amount and add slowly to avoid over-correction.

Best for:

professional pool maintenance onlywhen maximum pH increase needed

Very strong - use with extreme caution and proper safety equipment

Cooking Tips

💡Test pool water pH and total alkalinity before adding any chemicals
💡Add soda ash substitute slowly and in small amounts to avoid over-correction
💡Wait 4-6 hours between chemical additions to allow proper mixing
💡Run pool pump for at least 2 hours after adding chemicals
💡Retest water chemistry after 24 hours to ensure proper balance
💡Wear protective equipment when handling pool chemicals
💡Store pool chemicals in a cool, dry place away from other chemicals

Frequently Asked Questions

What's the difference between soda ash and washing soda for pools?

There's no difference - they're both sodium carbonate. Washing soda is the consumer product name, while soda ash is the industrial name. They work identically for pool pH adjustment.

Can I use baking soda instead of soda ash for my pool?

Baking soda can work but is less effective for raising pH. It's better for raising total alkalinity. Use twice the amount of soda ash for similar pH effect, or use washing soda instead.

How much soda ash substitute should I add to my pool?

Add 1.5 pounds of soda ash substitute per 10,000 gallons of water to raise pH by 0.2. Always add slowly and test frequently to avoid over-correction.

How long should I wait after adding soda ash substitute to my pool?

Wait at least 4-6 hours before adding other chemicals, and 24 hours before retesting water chemistry. Run the pool pump for at least 2 hours after adding chemicals.

Can I swim after adding soda ash substitute to my pool?

Wait at least 2-4 hours after adding soda ash substitute before swimming. Ensure the pool pump has run for at least 2 hours to properly distribute the chemicals.
