What is the cause of blue swimming pool water?
Blue-colored and blue tinted pool water is a common pool problem. Blue swimming pool water is caused by copper. It is important to know the source of your copper to prevent further issues. Using the images below, pick the type of blue water in your pool to get step-by-step directions for fixing your blue pool water problems.
Where does the copper in my pool come from?
It’s essential to identify the various sources of copper entering the swimming pool water. These sources include well water, which often contains high levels of copper, iron, and other stain-causing metals when used to fill or top off the pool. Additionally, high copper content in the source water can result in blue or green water and staining.
There are many sources of copper entering swimming pools. One major source is from copper-based algaecide. Copper coils in a heater is another large source of copper. When your pH goes below 7, your acidic pool water will eat away at the copper coil and any copper plumbing and fixtures and will add copper to your pool water.
Other copper sources include the presence of copper-alloy pool equipment, such as pumps and heaters, which can gradually release copper into the water. Additionally, copper-based algaecides and pesticides employed to control unwanted growth can contribute to copper accumulation if not carefully managed.
Chlorine tabs often contain copper (blue specks in the white tab). The plumbing system, particularly if it incorporates copper components, may gradually introduce small amounts of copper into the water. Water used to fill the pool might contain natural traces of copper, and runoff from copper roofs or nearby structures can exacerbate the issue.
Furthermore, copper-laden pool chemicals and even certain landscaping elements, like copper-containing ornaments, can also be sources of copper. It is important to prevent metallic debris, like coins or jewelry, or from construction, from corroding and releasing copper ions into the water. By identifying and addressing these copper sources, you can effectively prevent copper-related issues and enjoy crystal-clear pool water.
How do I get rid of copper in my swimming pool?
The secret to all metal removal, elimination, and stain prevention is CuLator Metal Eliminator and Stain Preventer!
CuLator is the only way to get rid of stain-causing metals like rust, iron, copper, manganese, and cobalt without draining your swimming pool water.
Patented CuLator allows you to remove and capture metals inside a small bag for easy removal. CuLator works in a wide range of pH and doesn’t dissolve in water, so it doesn’t add to your TDS. CuLator finishes what sequestering agents and metal control products start.
There are two sizes of CuLator:
A CuLator PowerPak 1.0 removes 1 ppm dissolved metals from 20,000 gallons and is placed into the skimmer basket. The CuLator Ultra 4.0 removes 4 ppm dissolved metals from 20,000 gallons of pool water. The Ultra 4.0 also includes a GatorEgg protective cage which allows the Ultra to be placed into the pump basket.
