Adding 2 oz. of sodium bicarbonate (baking soda) per 1000 gallons of water will raise the alkalinity 10 parts per million. Despite raising the alkalinity to the desired level in my vinyl-sided pool the pH was not adversely affected.

Increasing the pH of the water without affecting the alkalinity is very easy, but there is a trick. With the pump motor on and water circulating, add the sodium bicarb. in the deep end of the pool and work your way around the perimeter. This will raise the pH with minimal effect on the alkalinity.

Keep your pH around 7.6-7.8, not 7.2-7.4. Most "pool experts" tell you 7.2-7.4 but they are using an index that your local water company uses which obviously should not be used for pool. There's a big difference between a water treatment system and your pool. You can't treat them the same.

The chart you need is in the link below.

Yes, to raise total alkalinity. It will not raise pH Total alkalinity (TA) is a buffer for pH. the higher the TA in a pool the harder it is to get the pH to move.

Chlorine will not raise the total alkalinity level in a pool. However, if you are trying to raise the total alkalinity, you can add small amounts of baking soda.

Yes you can. In fact pool stores will sell you soda ash. It's pretty much the only place you can get the stuff. It will raise the Total Alkalinity and the PH of your pool.

Your question is confusing. You do not add alkalinity to a pool, alkalinity is a measurable component of a pools chemical balance. You normally only have to worry if a pools alkalinity is low and then the only impact is on the pool equipment. Baking soda is added to raise alkalinity, which is harmless to people so you can add baking soda to a pool while people are in it.

you need to bring your alkalinity up first using alkalinity UP
