7.4-7.6
No
Your Ph is probably out of whack it needs to be between pH 7.3 and 7.6 . If you do not have the equipment to test take a sample to your pool shop where they can do the check for you, and if you wish you can get test kits to do it your self. Keeping the pH of your pool correct will stop corrosion of pool equipment and aid in the effectiveness of pool disinfectants.
Sounds like the PH is wrong in the pool try adjusting to the correct PH
Everythging works better when the balance is correct, but you do not need to correct the pH before adding chlorine. Just keep an eye on it.
To raise the pH from 6.2 to 7.2, the pool worker should add an appropriate amount of soda ash or sodium carbonate to the water. It's recommended to follow the manufacturer's instructions for the correct dosage based on the pool size and current pH level. Regular testing and adjustment of the pH level should be done to maintain it within the desired range.
The main reason to ensure good ph (dull red in ph chemical test kit) is that as per the chemical tests, when at the correct levels the ph in the pool will leave a red trace cloud should any of your visitors be distasteful enough to wee in your pool
Add Acid
To lower the pH from 9.2 to 7.2, the worker should add an acid, such as muriatic acid or pH decreaser, to the pool water. She should follow the manufacturer's instructions on the product to gradually lower the pH level, frequently testing the water until it reaches the desired pH of 7.2.
Acid reduces Ph So by adding potash you will neutralise the acid and regain the correct Ph
Add base LEL
The shock will work better if the pH was within the correct range, but get the shock in asap, then do the pH.
It is not necessary to increase the pH before shocking a pool. However, adjusting the pH to the correct range (7.2-7.6) after shocking is recommended for optimal results.
