Honestly it depends on how high. An extremely alkali (high pH) pool can cause chemical burns with prolonged exposure. A pH of less than 10 is generally safe, though lower pH may cause discomfort in sensitive individuals after prolonged exposure.
High chlorine levels will make the pH in your pool high. You can add borates to help stabilize the pH level in your pool.
No
It depends on the volume of your pool and what level your Ph is at.
yes.. it has a low pH ... acid rain... so you need to add pH plus.
You will have to add an alkaline substance in order to get the kiddie pools water back to an acceptable PH level. Calcium carbonate would work to increase the PH.
After your pool is clear again, test the Ph of the water. You can purchase a test kit at your local pool or home and garden supply store. When the Ph of the water is at a safe level, you can dive in.
High pH
If memory serves me correctly, high PH is lowered with Calcium Carbonate. You probably want to consult someone who is licensed in pool care, however.
It may irritate your skin and in extreme cases cause blindness. Any pH between 6 and 9 will be okay to swim in but 7.2 is optimum. Measure it with an OTO test kit and add a little muriatic acid if the pH is too high.
Roughly somewhere between 5 and 30 minutes, depending on how much and how effective the chemical(s) put into the pool are and whether or not they are safe to swim in immdiately after they're mixed with the pool water.
Yes, but your eyes will turn red and you will most likely find that it stings your eyes. Too high and too low also makes your other chemicals in the pool far less effective. If it's too low, simply add baking soda until the pH rises to between 7.1 and up to 7.8, ideally 7.4. Hope this helps.
High level of anything is not good for you. High pH level can be damaging for one health. I would advise you lower your pH until it reaches the right level.
