Which one should I adjust first

[Sunny32504]

Okay I just heard from the pool store that 90 ALK is good for my pool and I thought it was suppose to be 120. Toooo late I added 4 1 lb boxes of baking soda Anyways I was also told by the pool store to add only 1 pint of acid in my 24' round pool which is I think about 17,000 gallons . Does that sound like enough . Thank you so much for the replies . Also if I shock my pool will it kill the bugs I have living in there also ?

Add half that then retest the pH in a few hours if you need more repeat.

A 24' round AG pool should only be around 13500 gallons, not 17000.

If you test a couple hours after you add the acid, you will find out if it is enough. Testing is the key - you need to know where you are and where you want to go before you start adding chemicals. It's better to add less and move closer to your target than to add too much and overshoot (for everything - pH Cl Alk CYA etc.)
