Usually the ph is tested with a phenol red indicator but litmus paper can be used
a swimming pool it should be neutral pH ie green
Chlorine levels, PH levels, Salt levels, stabilizer level, Make sure salt chlorinators are set correctly, check timing so that pool is filtering for enough time to produce required chlorine.
Not at all. A swimming pool should be between 7.4-7.6 pH Your's is too acidic.
raising the pH level of the swimming poolThe recommended pH-range for a swimming pool is between 7.2 and 7.8. To raise or lower pH, alkali such as sodium carbonate (soda ash) or sodium bicarbonate (baking soda) will added to the water. thanks hope it helps you heaps!!
When you add acid to a swimming pool it actually decreases the pH level you add soda ash to increase the levels http://sacpoolservices.com
No, not if the pool is kept clean, treated with the proper chemicals that maintain the proper pH levels, and cholorine to prevent the growth of fungi.

It could be out of balance chemically; it could have a dirty filter or it may have too much algaecide. Have you tested the pH lately.
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
Soda Ash
Lowers the Ph
High chlorine levels will make the pH in your pool high. You can add borates to help stabilize the pH level in your pool.
