The proper balance of chlorine in your swimming pool allows clean, safe and comfortable swimming. Too much chlorine in your swimming pool can be harmful to both the swimmers and pool itself. An over-chlorinated pool can fade and breakdown the swimming pool liner, corrode the filtration system, as well as irritate swimmer's eyes and skin. Testing your pool water and maintaining a proper chlorine balance will keep your pool safe and enjoyable.

Run your filter and wait it out. After testing your water, if you discover your chlorine level is high, run your filter eight to 10 hours per day for two to three days and then test again.
If you can not wait days for the chlorine level to fall, add 113 to 170gr of sodium bisulfite per 10,000 gallons of water in your pool. Sodium bisulfite is normally sold as a granular and is often labelled: PH- (pH minus). Run your filter eight to 10 hours per day to circulate the water and chemicals.
Test your water. Use water testing strips (found at any pool store) to test your chlorine and pH levels. Too high pH indicates too much chlorine in your water. 7.3 to 7.5 is the optimal pH level and 1.0 to 3.0 is ideal for a chlorine reading.
Tips and warnings
- For the most accurate reading, test your pool at least four times per week.
- Do not allow swimming if the chlorine level is over 3.0 as it can cause eye and skin irritation
