Ideal Chemical Levels for Your Pool

Proper Chemical Balance in Pools

Maintaining chemical balance in your swimming pool’s water is essential for keeping algae and bacteria at bay as well as ensuring that the water is safe and comfortable for swimmers.  Here’s a quick reference guide that gives you the ideal chemical levels and recommendations for how to raise or lower the levels if they are out of balance:


  • Ideal level = 2.0
  • To raise chlorine levels = Shock the pool
  • To lower chlorine levels = Turn the chlorinator down


  • Ideal level = 7.4 (Summer), 7.8 (Winter)
  • To raise pH = Add soda ash
  • To lower pH = Add muriatic acid (diluted) into the pool with the pump running to ensure that the acid spreads throughout the water as quickly as possible.

Total Alkalinity

  • Ideal level = 80-100 ppm
  • To raise total alkalinity = Add baking soda
  • To lower total alkalinity = Add muriatic acid to the deepest part of pool while the pump is off.  Allow this to sit for at least 20 minutes, then turn the pump back on.

Calcium Hardness

  • Ideal level = 250-500 ppm
  • To increase calcium hardness = Add calcium chloride
  • To decrease calcium hardness = Drain pool and refill


  • Ideal level = 20-50 ppm
  • To raise stabilizer levels = Add cyanuric acid
  • To lower stabilizer levels = Drain pool and refill

Keep the P and Poo Out of Your Pool: Tips for Healthy Pools

Pool Signs

Pool signs, like the one above, are a funny way to remind those who swim in our pools that the pool water is not a bathroom.  Contamination of water, though, can be a serious problem.  If a pool’s pH level is out of balance, the chlorine is unable to effectively kill harmful germs that are introduced into the water by swimmers.  Everything from dirt to sun to leaves and other debris can alter the pH level of pool water, so checking the pH level on a regular basis and adjusting the chemical balance as necessary is a crucial step in maintaining a healthy pool.

In addition to ensuring that there are always correct levels of chemicals in your pool’s water, you should insist that all swimmers follow these three rules to avoid contaminating the pool water:

  • Never swim when you are sick.  Germs can be spread to others in the pool.
  • Avoid swallowing pool water or getting water in your mouth.
  • Keep yourself clean.  Take a shower and soap up before taking a swim, and don’t forget to wash your hands after going to the bathroom or changing a diaper.  Even the smallest amount of contamination on your body can be transferred to pool water and cause illness in others.

Being a diligent pool owner will help prevent the spread of germs and illnesses and keep your swimming pool a healthy place for everyone to enjoy.

Maintaining Balance Through All Kinds of Weather

Pool Chemical Balance

Did you know that a heavy rain shower can throw the chemicals in your pool water out of balance?  When the amount of water in a pool changes, whether due to heavy rain or evaporation, the balance of pool chemicals must be adjusted to maintain ideal levels.  Here’s why it’s important:Pool Chemicals

  • Ideal levels of pool chemicals prevent dangerous bacteria from thriving in pool water;
  • Water that is chemically out of balance can actually damage parts of a pool;
  • Eyes and skin can become irritated easily when pool chemicals are not balanced.

Testing your pool’s water frequently is highly recommended, and using the appropriate amount of pool chemicals to bring the water back into balance is an important step in keeping the water safe and your pool in good working order.
