It’s almost spring, so it’s time to prepare your pools for the new season. Aqua Blue Custom Pools has partnered with us to bring you the latest information on how to test your pool’s water properly. Let’s get into the details!
Having a pool is great fun, but it is crucial to keep it clean. While most people are familiar with testing for pH balance and chlorine levels which is essential, they often neglect to check for potential contaminants such as iron or calcium.
These chemicals can cause your pool to look uninviting and damage your collection. It is simple if you know how to test your pool water.

How to Pool Water Test (and Why It's Important)

It is vital to test your pool water. It is essential to test your pool water for contaminants. Although trace contaminants may not seem to be a significant problem, they can become severe over time. To avoid potential issues, it is essential to test your water every so often.
First, you will need a water sample, and these are the steps to ensure a precise reading.
  1. Use a clean cup.
  2. Place the opening in the middle of the pool.
  3. Turn the cup upside-down to fill it.
Once you have the sample, you can test it with strips or a liquid testing kit. You also have the option to take it to a pool store that specializes only in sales and maintenance. Always read and follow the instructions for every method. Take your time. You will not get the results you want if you rush this or do it wrong. It is a good idea to test your pool water once per week. If you use your pool frequently, or if there has been recent rain, it may be necessary to try the water more often.

Here are 5 Common Pool Water Contaminants and How To Test For Them

There are many reasons that contaminants can build up in your swimming pool water, and it's often due to the quality of the water that you use in your pool. Water may contain many minerals, which can lead to high levels of iron and copper, while city water is often high in calcium.

Copper Testing

Your pool water can become cloudy due to copper buildup. Copper buildup can occur due to copper in tap water. The pool testing strips used in most pools do not test copper, and you will need copper testing strips. Either add a copper sequestrant to prevent corrosion or use a metal trap filter.

Test for iron

High levels of iron are usually indicated by brown or rusty water. Low pH levels can cause iron levels to rise, similar to copper. However, it could also be due to natural levels in your water source. Good news! Most copper test strips also check for iron. You will need to add an iron-verifying solution, which should be done about once per month. You can also use the same methods to treat copper as iron.

Calcium Testing

Your pool filter and pump can also be affected if calcium buildup occurs in the faucets. It is essential to maintain a balanced calcium level. Too much calcium can lead to corrosion and cloudy water. However, too little can cause concrete pool surfaces to disintegrate and pit. The best pool water testing kits can test for calcium, pH, and chlorine. Calcium should be between 200-500 ppm, and you can add muriatic acid to make it less hardy.

Test for Phosphates

Phosphates can cause algae growth, and you don’t have to test for them. Adjusting your phosphate levels will not eliminate algae, contrary to what many believe. Make it E-Z Here!
You can use an algicide free of copper to prevent algae from growing. To prevent algae growth, keeping your chlorine levels stable and maintaining a proper pH level are essential.

Test for salt

Saltwater pools need to be balanced. Salt can cause damage to your saltwater chlorinator, and water can become unsanitary. Salt? Have salt? Get pepper!
Specialized testing strips are required to test for salt levels. It would help if you aimed for 3200ppm. You can fix high levels with more water; for low levels, you can add salt. Continue testing until you achieve the perfect balance.

Last Thoughts

To avoid pool damage or to prevent anyone from getting sick, you must test your pool water regularly. It’s easy to make your pool last for many years with the right tools.
