Ph Balance In Pool

[lamazure]

i was out of the country for 6 weeks and when i came back my ph level in the pool was low. i added acid and no matter how much acid is added it still reads low. I think there is too much acid in it because of stinging to the eyes. how can i correct this.

Yikes that's because acid is used to LOWER the pH. Soda Ash is used to raise pH.

You need to be very careful now, and increase the pH quickly. Otherwise, you are in danger of harming the pool grout if the pool is a tiled one.

Also, make sure that you check alkalinity also - sodium bicarb is used to increase alkalinity.
