Why is the Ph Level so Important for your Swimming Pool? The Ph level of your swimming pool is one thing you definitely need to keep a close eye on. Each week you should be using a testing kit so you know what the levels are. Ideally you want them to be as close to 7.2 as possible. However, anything in the range of 7.0 to 7.6 is deemed as acceptable and you won't need to do anything else about it. However, if the level is too high or too low than you need to balance it out by adding various chemicals. If the amount is below 7.0 then it is considered to be too acidic. If the amount is above 7.6 then it is considered to be alkaline.
