How Much Baking Soda To Raise Alkalinity

Add baking soda if the ph is below 7 2 and the total alkalinity is below 80 ppm.

How much baking soda to raise alkalinity.

Sodium bicarbonate aka baking soda is one of the most useful compounds in the pool industry. In order to know how much of either substance to dissolve in your pool you need to first calculate your pool s total water volume. The question was a bit vague as we needed to know the existing ph reading and also the volume of water in the hot tub to give a proper answer. Baking soda sodium bicarbonate isused to raise alkalinity and also slightly raises ph and soda ash sodium carbonate is used to raise ph and slightly raises alkalinity.

To raise your alkalinity levels you ll add sodium bicarbonate baking soda to your pool water. This means you will need to add roughly nine pounds of baking soda to a 20 000 gallon pool to raise the alkalinity by 30 ppm and achieve the minimum alkalinity goal of 80 ppm. Additionally it alkalizes bodily fluids including the blood and urine. Add the baking soda directly to the pool let it dissolve and give it time to distribute through your pool s water at minimum 20 minutes with your pump running test and add more baking soda if needed.

As per standard 1 25 pounds of baking soda is enough to raise the ph level of a 10 000 gallon pool by 10ppm so to achieve a 100ppm alkalinity you would need 12 5 pounds of baking soda for a 100 000 gallon of pool water. Test the water for ph and total alkalinity using test strips or a pool test kit. If the ph is low but the alkalinity is in the proper range use soda ash to raise the ph. How much baking soda does it take to raise alkalinity.

While baking soda can be used to raise the ph of your hot tub s water it will only raise the ph slightly. Recently we were asked the question how much baking soda was needed to raise alkalinity in a hot tub. You will want to use one tablespoon of baking soda per every one hundred gallons of water in your hot tub. To lower it you ll use muriatic acid.

Use our calculator below to figure it out. Substances like alka plus aka buffer or alkaline increaser are all products used to increase the alkalinity of a swimming 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. Baking soda is mostly used to raise the alkalinity of your hot tub s water.

Your swimming pool alkalinity can be improved by the following methods. Remember the proper level for ph should be between 7 2 and 7 8 parts per million.
