Water burns eyes:
Your pH may be too low or too high. Use a water test kit to determine the pH level and adjust it to a 7.4-7.6 range. Another item to check is whether or not there is too much sanitizer in your pool. Check the automatic chlorinator setting.
Water is sudsy:
Pool water can turn sudsy from the overuse of algaecide. Some types of algaecide can cause water to foam when used liberally. To fix the problem, discontinue use of your current algaecide and switch to a high-quality, non-foaming brand. You may also want to replace some of the pool water with fresh water. Products that help stop foam are available from pool supply companies.
Water is salty:
This is often caused by high total dissolved solids (TDS). TDS is high if it measures over 3,000 ppm. To correct the problem, drain half of the water from the pool and replace it with fresh water.
Should I take a water sample to my pool supply store or can I do the tests myself?
You can test the pH level with a home test kit available at most pool supply stores. TDS levels is more complicated but there are some portable devices available at a reasonable price. If you prefer you can always take a sample water to your pool supply store or contact a professional pool supply company.
Sound advice. Sometimes is necessary to check for too much chemicals in the water. If you are not sure how to balance your water to keep it clean and clear you should contact a professional pool service company.
