After this treatment test your ph and alkalinity and add baking soda to raise alkalinity to at least 100 ppm and ph to between 7 2 and 7 8.
How much baking soda to raise alkalinity in pool calculator.
Your swimming pool alkalinity can be improved by the following methods.
Baking soda sodium bicarbonate isused to raise alkalinity and also slightly raises ph.
Add baking soda if the ph is below 7 2 and the total alkalinity is below 80 ppm.
If the ph is low but the alkalinity is in the proper range use soda ash to raise the ph.
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.
Test the water for ph and total alkalinity using test strips or a pool test kit.
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.
Check total alkalinity levels often.
Desired increase in total alkalinity 10 ppm 20 ppm 30 ppm 40 ppm 50 ppm 60 ppm 70 ppm 80 ppm 90 ppm 100 ppm.
High alkalinity means your pool water is buffering too much and possibly diluting the effectiveness of chlorine to the point it is unable to sanitize some contaminants in your pool or hot tub.
Substances like alka plus aka buffer or alkaline increaser are all products used to increase the alkalinity of a swimming pool.
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.
To raise your alkalinity levels you ll add sodium bicarbonate baking soda to your pool water.
Total alkalinity is the measurement of a pool or spa s susceptibility to ph change.
Baking soda and pool corrosion if you re noticing corrosion on your pipes or ladders or pits on your pool liner or tiles you have very low water alkalinity.
How to lower pool alkalinity.
Use our calculator below to figure it out.
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.
Total alkalinity that is out of range allows for large rapid ph swings.
And soda ash sodium carbonate is used to raise ph and slightly raises alkalinity.
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.
To lower it you ll use muriatic acid.
Extreme ph changes also called ph bounce throw the water out of balance causing a number of potential problems such as ineffective chlorine metal corrosion staining scaling and even physical.
