Question: Does Shock Bring PH Up?

Can I add shock and algaecide at the same time?

While shocking and adding algaecide is effective in getting rid of algae, it should not be done together.

This is because when you mix chlorine and algaecide together, it renders both of them useless.

Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM..

Does shock raise pH?

Wait about 20 minutes, and you are free to swim. We suggest adding algaecide, Super Erace, and shock at night, after everyone is out of the pool.

How long after shocking a pool will the green go away?

Can I add pH up and alkalinity at the same time?

To raise pH and Alkalinity at the same time, start with Alkalinity, and add enough Increaser to raise Alkalinity to 100 ppm. Add 1 lb Alkalinity Increaser per 10,000 gals, to raise Alkalinity 10 ppm. The pool pH level may rise and follow, without added pH Increaser.
