When you shock a pool with metals in the water, the metals will oxidize. If there are enough metals present in the water, this process can turn the water green. If left untreated, the problem will continue to get worse and will stain the finish of the pool, potentially permanently. Anyone with blonde hair that swims in a pool with excessive metals will also have their hair turn green.
So now that you know the possible causes of green pool water, the question becomes how to tell which one is affecting your pool. To do that requires some troubleshooting. The first thing to do when troubleshooting the cause of green pool water is to look at the pool itself as each potential cause of green water has subtle differences in how they make the water look.
Algae will start to grow on the pool walls and bottom first. It is usually dark green will feel slimy to the touch. As the algae bloom worsens the water will begin to look swampy; consistently dark green and impossible to see more than a few inches into the water.
Like algae, pollen will first become visible on bottom of the pool. For this reason it is often mistaken for green or yellow algae. Unlike algae however, pollen does not stick to the pool surface. If you wave your hand a couple of inches over the affected area without touching it , pollen will puff up like a cloud where algae will not move. Pool water turned green by metals will be a consistent light green colour; looking almost as though the pool has had green food colouring added to it.
Despite the colour, the water will still look fairly clear and you should be able to see the bottom of the pool. Metals can also stains to appear on the surface of the pool. Bringing along some photos of the problem can also be very helpful.
When going over the results of your water test, pay close attention to chlorine and copper levels in the water. If there is no chlorine present in the water, and the water is a dark green, then the most likely cause is algae. It may seem logical to wish to vacuum the algae, but the goal is to kill it. For that, the algae must remain in the pool.
This process kills the algae. Chlorine must be used for this, even if your regular shock does not contain it.

As the Olympics example illustrates, when chemicals in a pool or spa are out of balance, the water can start to look funky. Whether you operate a country club, a public pool, or a water park—or you have a pool in your backyard—maintaining proper water characteristics conveys an alluring aesthetic. Even if water that appears green is safe to swim in, many people will probably decide against getting wet. Water that has too much chlorine in it can irritate the eyes, skin, and lungs.
Chlorine makes water more acidic; improper balances can corrode piping, pool equipment, and certain pool surfaces i. That said, chlorine is an essential ingredient in clean pools.
