Is alkalinity dangerous for humans in swimming pools?

Alkalinity is not an actual "chemical", however if you are concerned about increasing the alkalinity in your swimming pool, you are perfectly safe. The chemical that increases "total alkalinity" in a swimming pool, is only baking soda. It wil not harm the human body!

Does baking soda lower or raise ph in a swimming pool?

Neither. Baking soda raises the Total Alkalinity. Soda ash raises the pH.

Will muriatic acid lower pool water hardness?

Muriatic acid will not lower the Harness(calcium chloride)level in a swimming pool. Dilution is the only effective method to lower the calcium hardness level. Muriatic acid is used to lower the pH and total alkalinity of pool water.

How do you lower alkalinity but not change pH in a swimming pool?

Initially, you can't. What you do to lower alkalinity is first lower the pH to under 7.2, but not lower than 6.9. Then you aerate the pool, by creating bubbles with your brush, or by running a water feature, if you have one. This will lower your alkalinity. Maintain this lower pH and aerating until you get your alkalinity where you want it. Then retest your pH. If it is now too low, you add Mule Team Borax, say a 1/4 a cup, and then retest. The borax will raise your pH without raising your alkalinity. See the for more help if needed.

Muriatic acid uses for swimming pools?

Muriatic Acid is used to lower the pH in swimming pools. It's also used to lower alkalinity. But, there's a way to lower pH and really not touch the alkalinity, and vice versa. pH and alkalinity and opposite sides of the same coin and you need to know how to add the acid with minimal effect on the other side. give all the information you need

Can you use baking soda on the pool?

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.

Can baking soda be used with water?

Since your question is in the "pool care" section I will assume you mean swimming pool water. In that case, YES, sodium bicarbonate is used to adjust pH and total alkalinity.

What do you use to raise the ph in a swimming pool?

the pH can be raised by adding an alkaline chemical such as soda ash (which also raises total alkalinity quite a bit) or borax (which has only a slight effect on total alkalinity), or by aeration of the water to outgas CO2 (which will raise pH with no impact on total alkalinity). Soda ash actually has very little effect on Total Alkalinity. Baking soda is the chemical to use to raise T/A.
