Baking soda can be very useful for homeowners who have hot tubs, as it can help them keep the pH of the water in the right zone. As many homeowners know, the ideal pH value for a hot tub or pool should be between 7.2 and 7.8. If the water is too acidic, the heating element will wear out quickly. Baking soda can increase the alkalinity of the water and bring the pH back to an appropriate level.
Baking soda can increase the pH value of your spa. But it affects the alkalinity more than the pH. Because of its minimal effect on pH, it can take a pound of baking soda to significantly affect your pH. Sodium carbonate or magnesium oxide are much better alternatives to increase the pH in your hot tub.
How much baking soda to increase the pH in your hot tub
But to return to the amount of baking soda needed to increase alkalinity in hot tubs; using everyday household items that you may already have in stock instead of waiting days for a factory-made chemical to arrive adds even more excitement and doubt to your thoughts about corrosion…
Things you will need
– Water test strips
– Soda Baking
– Measuring spoon
Regularly draining and refilling a hot tub maintains the correct pH value without adding any additives to the water.
Baking soda (1 gallon pail) made of pure organic ingredients, highly pure, aluminum-free, food & USP quality, for cooking, baking, cleaning, & More! All you need to do is sprinkle an ounce of baking soda into the water of a 250/300 gallon hot tub and let it dissolve naturally – twenty minutes should be enough, then turn on your pump for an hour before checking the pH again.
If it is still acidic, just repeat it until it gives the right pH!
It shouldn’t take more than a few hours, then jump in and enjoy!
How do you reduce alkalinity in a hot tub?
The two most popular chemicals that help you reduce total alkalinity in your spa are muriatic acid and sodium bisulfate (also known as dry acid). After adding muriatic acid, dry acid or any other alkalinity reducing product, you should check the pH in your spa because the pH may have dropped.
By keeping your pipes, filters and water clean, you avoid most chemical problems and the effects that poor water chemistry can have on your spa and your health. Remember to change the water completely, at least every three or four months, so you don’t have to fight to balance the dirty water.
The industry standard has always been to use sodium bicarbonate (baking soda) to increase total alkalinity and sodium carbonate (sodium carbonate) to increase pH – the exception is when both total alkalinity and pH are low. Realizing that it is impossible to increase (or decrease) one without chemically affecting the other, there is still an analogy to the “right tool for the job” that comes into play.
Stick to a spa water maintenance plan that works for you and your spa, and you will have most water problems before they even arise.
