How to Increase Alkalinity In A Pool?

Do you realize that the reduction in alkalinity level increases the acidity in the pool? The acidic water is dangerous for swimmers and the lifetime of the swimming pool. If your pool has become acidic, you need to repair the pool. The problem is that it is difficult to check the alkaline level of your pool at first sight. It may look bright but have an unsafe alkalinity level. 

So, Let’s know how to notice and increase the alkalinity level in a pool.

Why is it paramount to increase your alkalinity level?

If the alkalinity level is high in your pool, it may be dangerous for the pool. It increases the risk of wall etching, cracking down, and delamination. Some metals will provide the source to melt in the alkaline water, resulting in stained walls. 

Even little changes in pool water and any chemical changes may cause acute fluctuations in the pool’s water pH levels. If the pH level of your pool is disturbed, this phenomenon is known as pH bounce and may decrease the alkalinity in your pool.

When alkalinity is low, adding chlorine to your pool may be impractical. It will only show the standard results when you will add a larger amount of chlorine than usual.

You should maintain your pool’s alkalinity because the higher level may cause eye and nasal infections in the swimmers.

What are the reasons for low alkalinity in a pool?

These are the main reasons for low pool alkalinity

  • If you use dry acid, it may be good to treat swimming water but may decrease the pH level of the pool. The way to maintain the alkalinity and pH level is to add a proper amount of chemicals. After 6 hours, you can check the alkalinity of your pool. 
  • Hard rainwater is dangerous and can increase alkalinity levels. In the hard rain, floods may occur in your pool. 

How to increase a swimming pool’s alkalinity?

Keep these measures in your mind to increase the alkalinity in the pool. 

The first is your pool and range. Your pool size must be between 80 to 120 regions per million. The experts may demand that you hold in the 100-120 ppm range. 

These methods also help to improve the alkalinity level of your pool. 

Use baking soda:

Sodium bicarbonate is the most beneficial compound in the waterhole industry. Essences such as alka-plus or alkaline boost all products utilized to improve the alkalinity of your swimming pool. Baking soda is the best chemical to boost alkalinity levels; easy to find and affordable. 

You can buy sodium bicarb from any retail store or a waterhole supplier – the identical compound. The singular dissimilarity is that purchasing from your pool supplier arrives with bonuses like instructions on utilizing it. You will not be offered such instructions if you buy it from a retail shop.

The procedure of using sodium bicarbonate to increase pool alkalinity:

  • Test the overall pool alkalinity: Encountering the whole alkalinity status of your swimming pool will decide if you require to enhance or lower it. If, after looking, your pool alkalinity is less than 80 ppm, it is the moment to calculate the pH level.
  • Purchase enough sodium bicarbonate: In the case of too much lower alkalinity, adding 5 Lbs of baking soda to the pool is not enough. Please add an extra amount of this chemical. Talk to your expert pool supplier and discuss your problem of how much quantity of baking soda is required to add to the pool. 
  • Dilute the baking soda: An instruction is written on every sodium bicarbonate container to dilute it before use. So, please don’t ignore it.

How to Increase Alkalinity In A Pool? Procedure

  • Know the right amount to add:  Too down an alkaline status in your swimming pool would create water acidity. Too elevated? Just like many troubles. The important thing is to understand the right quantity of baking soda in your low-alkaline pool. Half and three-quarters of the baking soda is enough to reach your needs. If you can add more baking soda after counting this portion, your waterhole alkalinity is yet down.
  • Flow It In The Pool: Baking soda is water-soluble that liquefies fast. You can add a suggested portion into your pool to raise alkalinity. Avoid spraying completely in one location, and avoid adding this at a place where the air is present because the chemical particles may be frittered into your eyesight and mouth.
  • Check it After Some Time: After adding the chemicals to your pool to improve alkalinity, you should check it to know the effects after six hours. If you do not retest it in six hours, you should check it in 24 hours.

If the pool alkalinity is still finished after running through these methods, you can retest the procedure until the alkaline amount becomes stable.


We concluded that an adequate alkaline level shows a fine swimming pool. Lower alkalinity tells destruction for your pool or the swimmers and may be controlled by frequent examinations and tests. 

Your swimming pool style also defines the beneficial ppm range of the water. If you hold concrete, mirror, gunite, or shotcrete pool externals, enough ppm range is about 100 –120.
