The fastest way to clean a green pool is by using pool chemicals and your pool filter. This process usually takes around 4-5 days but you will start noticing a major improvement after 24 hours.
Most often, the remedy for a green pool is to shock it. To properly clear green pool water, you'll need to clean the pool tiles, filters, and equipment thoroughly, add shock and algaecides, and rebalance your pool water. The entire process to fix a green pool usually takes a few days.
Shock Your Pool
We recommend using a calcium hypochlorite shock to treat your algae problems. However, green, yellow, and black algae will each require their own level of shock in order to be completely killed and removed from your water.
Baking Soda
You can even use it on your concrete or stone pool deck. This is probably the easiest and least expensive way to clean your pool naturally. Bonus Tip: Baking soda will also increase your pool's alkalinity, and is far less expensive than most alkalinity increasers.
Pools can immediately turn green after shocking when they have metals like copper in the water. These metals oxidise when exposed to high levels of chlorine which makes the pool water turn green. Adding a metal control product such as Zodiac Metal Remover will help to restore the pool water.
When the levels are properly balanced, chlorine will keep the algae at bay, but the water will slowly begin to turn green as the algae take over if there's not enough. But be careful—adding too much chlorine in pool water can cause those metals to oxidize and turn the pool a different shade of green.
The most important test to take if your pool's still green after shocking is the pH level. Buy a kit or a test strip and test the pH because it will indicate whether you need to add other chemicals. A high pH means your water is alkaline and cloudy, especially after the shock.
Does baking soda kill algae in pools? Only algaecides can "kill" algae in pool water. However, baking soda can help clear up algae. Use both so you can restore sparkly, clean water!
In the same way that baking soda can be a spot treatment for black algae, household borax does the same for blue and green algae. Simply use the borax to scrub away algae that's sticking to your pool walls, then use the brush to dislodge it. Follow up by vacuuming up or scooping out the free-floating algae.
A good way to do this is buying 25 gallons of chlorine and adding three, four, or five gallons at a time. The huge amount of chlorine will work to kill the algae. The best and fastest way is to use a shock that contains at least 70% chlorine. If your pool is really green, then you may need to add more shock.
The fastest way to clear cloudy pool water is to use shock. If the pool's chlorine levels are low, it can lead to cloudy water. Shocking the pool will help to raise the chlorine levels, killing any algae or bacteria present in the pool. Use a chlorine shock product and follow the instructions on the label.
There are a lot of reasons why algae keep returning to pools. The most common of these reasons are: Low levels of chlorine or chlorine getting burned up too fast before it gets the opportunity to kill the algae.
During a no-drain acid wash, you keep the water in the pool. Instead of spraying the pool's walls and floor, you reduce the water's pH level to make it acidic with no alkalinity. Then, scrub the pool's surfaces to peel its out layer manually.
The only thing that kills algae is CHLORINE (or your sanitizing product, or one of the copper-based algaecides on the market). You need to raise the level of your chlorine – shock the pool – and maintain that high level until all the algae is dead. This may take 3 to 4 days. RUN THE FILTER 24 HOURS A DAY.
The green color in the water means that there is algae present, and the only thing that will get rid of algae is a sanitizer (chlorine). Sometimes just putting one chlorine tablet just isn't enough chlorine.
In general, add one pound of shock to your pool for every 10,000 gallons of water. But if you're experiencing an algae problem, you'll need to add double, triple, or quadruple the amount of shock.
It may surprise you to learn that algaecide isn't a magic bullet for getting rid of algae in your pool. In fact, algaecide is more effective as a preventive measure than a treatment. Don't get us wrong—it still helps as an algae treatment, just not in the way you might think.
If the pH is high, your chlorine is slow to react, and algae can begin to form, making the pool appear green or cloudy. If the pH is low, the chlorine will be “hyperactive”, reacting quickly, and dissipating out of the pool too rapidly, causing a low chlorine residual.
Algaecide should be used after each shock treatment, so it has a better chance to support your chlorine as it works its magic. Be sure to shock your pool first, then when the chlorine levels of your pool return to normal, add the correct amount of algaecide to several places around your pool while your pump is running.
Algae is attracted to bacteria and parasites. These microbes can enter the body through the nose, eyes, ears, mouth, or a tiny cut. In this situation, it is less safe to swim in green pool water. This is why regular chemical testing is so important.
