Shock the pool with chlorine every day until all the green is gone (possibly 3 to 4 days). 2. Run the filter 24 hours a day and backwash every day until the green and then cloudiness is gone (usually up to 7 days, sometimes as long as 2 weeks depending on the filter). 3.
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.
If your pH is not too high, filtration issues are likely the cause of your cloudy pool. The issue may depend on the type of filter. If you have a sand filter, it could take a week or more for the pool to completely clear. That's even if it's a working sand filter.
Can you over shock a green pool? No. The more chlorine shock you add to a green pool, the better chance it has to kill off all the algae. Follow the normal shock treatment based on the size of your pool and you can double, triple, or quadruple the dose to kill algae.
Green or Dark Green Pool Water:
This means there's a medium amount of algae in your water and you'll need to triple shock your pool. Triple shocking requires 3 pounds for every 10,000 gallons of pool water.
It's pretty tough to over-shock your pool; shocking your pool two days in a row with the proper dosage for your pool volume shouldn't be a problem – and in fact, is sometimes even needed to rid your pool of algae and other contaminants.
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.
You need to wait for at least 8 hours and up to 24 hours after using a chlorine-based shock before you can swim.
1. Shock the pool with chlorine every day until all the green is gone (possibly 3 to 4 days). 2. Run the filter 24 hours a day and backwash every day until the green and then cloudiness is gone (usually up to 7 days, sometimes as long as 2 weeks depending on the filter).
Typically, algae is the source of green pool water, and it's certainly possible that it took over quickly, even overnight. This is especially likely if it is very warm outside, since algae blooms more rapidly in warmer temperatures.
Light Green or Teal Green Pool Water (early-stage algae): Double shock your pool with two pounds of shock per 10,000 gallons. Darker Green (significant algae growth): Triple shock your pool with three pounds of shock per 10,000 gallons.
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.
The more you filter than backwash, the faster that your pool will become clear. For DE Filters, remember you need to add more DE to your skimmer as close as you can to filter backwashing. Run the filter for 24 hours and backwash the pool filter around 4 times during the same day to get faster results.
While this high level of chlorine is effective at killing off unwanted organisms, it can also cause your pool water to become cloudy. The water may also have a strong chlorine smell. If you experience any of these symptoms, you should stop shocking your pool and contact a professional.
Adding too much shock or overshocking your pool will kill off algae. The negative of adding too much shock is it will upset the chemical balance of your pool.
Sun Down – You'll want to shock your pool in the evening when the sun has gone down. This gives your pool plenty of time during the night to free the chlorine and clean the water. In the morning, you should be able to enjoy your pool. If you shock your pool during the day, the sun's UV rays will dissolve the chlorine.
Keep your pump and filter running. Give the shock a good 12 to 24 hours to work its magic. If the algae hasn't cleared up after 24-48 hours, clean and brush the pool and add another shock treatment.
Calcium Hypochlorite: Also referred to as cal hypo, this chemical is one of the least costly and most convenient ways to shock your pool. It's usually sold in granular form. Needs to be dissolved before you add it to the pool. Must be used after dusk.
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. But never fear, it's impossible to over shock a pool. You can get chlorine in both powdered and liquid form, but liquid chlorine works faster if you're in a hurry.
Cal-hypo is the best shock treatment for you. It's powerful enough to kill contaminants and stop algae growth (similar to an algaecide). However, it may require multiple doses, depending on your situation. It's a powerful weekly treatment for your pool, especially if you deal with ongoing green water or cloudy water.
If you have recently done a Pool Shock Treatment for your pool, you might be a little worried if there is still cloudy pool water. Don't worry, your treatment has not gone into waste. Even if you shock your pool properly, it takes a while for the natural microorganisms to do their job.
