How to raise the alkalinity in a pool

How do I raise the pH and alkalinity in my pool?

A rule of thumb is 1.5 lbs. of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm. If your pool’s pH tested below 7.2, add 3-4 pounds of baking soda. If you’re new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount.

How do you increase alkalinity?

The industry standard has always been to use sodium bicarbonate (baking soda) to raise total alkalinity and sodium carbonate (soda ash) to raise pH — the exception being if both total alkalinity and pH are low.

What causes low alkalinity in pool?

Even the slightest alterations on pool water chemical composition can cause severe fluctuations in the pH levels. When the pH level becomes unbalanced, the phenomenon is called pH bounce and can cause low alkalinity in the pool, as the case may be.

What should be adjusted first alkalinity or pH?

You should test alkalinity first because it will buffer pH. Your reading should be in the range of 80 to 120 parts per million (ppm). If you need to increase the alkalinity, add an increaser. To lower it, you’ll add a sodium bisulfate.

How do I raise the pH in my pool without alkalinity?

It’s best to shock a pool with a low pH range of 7.2-7.4. Alkalinity is closely related to pH, and when it’s too high, it can prevent you from lowering your pH easily, and it can easily throw off bicarbonates, which make the pool cloudy.

Is alkalinity increaser the same as baking soda?

Although both products are similar, they are not the same. It is very common to use sodium bicarbonate (baking soda) to raise total alkalinity and sodium carbonate (soda ash) to raise pH — the exception being if both total alkalinity and pH are low.

Does Shocking a pool raise alkalinity?

Typically goes hand in hand with pH. If the alkalinity reading is low, then most likely the pH reading is low and visa versa.
