You didn't use Flocculants or Clarifiers. If you still can't see the bottom after shocking your pool, you may need to add a clarifier or flocculant the next day to remove the dead algae. Flocculant binds to small particle impurities in the water, causing them to clump together and fall to the bottom of the pool.
It is quite normal for a pool to turn cloudy after such a huge shock treatment. The shock you used is ``calcium hypochlorite'' and the large amount of calcium is responsible for the cloudy pool water. Filter round the clock and it should begin clearing on its own within a few days.
In general, it typically takes about 24 to 48 hours for the shock treatment to fully take effect and for the water to clear up. However, it's important to note that shocking a pool is not a one-time solution.
Why is my pool still green after shock? Algae may not be fully killed by shock. Filter may not have picked up all remains. Cloudy water is normal after shocking. Keep running clean filter and add a clarifier or a flucculent to speed things up. Is your pool water green? Here's how to clear it up by just adding shock.
It could be you didn't add enough chlorine. It could be that didn't brush the pool well enough first. It could be that your filter isn't performing as well as it could or just needs more time.
Is it possible to shock your pool too much? Yes—excessive shocking of your pool will keep it at an elevated chlorine level. This will cause irritation of the skin and eyes as well as excessive wear and tear on your pool filter system, including excessive corrosion of all metal parts.
The shock you used may be expired or isn't strong enough. It is also possible that you didn't use it correctly. The ideal shock dosage is 1 pound per 10,000 gallons of water. But you may need to put more depending on the level of algae infestation.
Steps for Preventing Algae
If your pool is used frequently, shock it at least once a week.
When: Add a water clarifier to your pool at least a day after the shock treatment has finished. You could use a combination of the two with Clean and Swim's non-chlorinated shock treatment and pool water clarifier.
Let the shock try to fight the algae first. Add algaecide about 24 hours after shock to finish the job and prevent future algae blooms.
Adjust the pH and alkalinity levels using Caribbean Blue Chemicals. Brush the walls and floor of the pool to dislodge algae, then shock the pool with a high dose of chlorine to kill the algae. Run the filtration system continuously until the water clears.
If the pH gets higher than 7.8, the water is becoming too alkaline. When water is too alkaline, it reduces the effectiveness of chlorine — the pool chemical that kills pathogens. Water with a pH that's too high also can cause skin rashes, cloudy water and scaling on pool equipment.
It's normal to see cloudy water after shocking your pool. That's dead algae and contaminants suspended in the water. Use a clarifier or flocculant to clear up your water. . . . . . .
Environmental reasons like bird droppings, flower pollen and run-off. The chemistry of your pool water, including chlorination, pH and alkalinity levels. Inadequate circulation caused by blocked skimmer boxes. Dirty or damaged filtration equipment that needs repairing or replacing.
If you've got any pool toys or brushes that you want to disinfect, now's the time to drop them in the pool. Most shocks will take about 8–12 hours to work. For those using non-chlorine shock, 15 minutes should be enough to circulate the product and sanitise your pool.
Liquid Acid (Hydrochloric Acid or Muriatic Acid)
Evenly pour the liquid acid around the edge of the pool, avoiding splashing or pouring outside the pool. Allow the acid to mix with the pool water. Test the pH levels again in 4-6 hours to confirm the desired level has been achieved.
If you still can't see the bottom after shocking your pool, you may need to add a clarifier or flocculant the next day to remove the dead algae. Flocculant binds to small particle impurities in the water, causing them to clump together and fall to the bottom of the pool.
Too much clarifier makes your pool cloudy and murkier than before.
It's all to do with your pool's pH. Pool expert Rafi Friedman told me that 'Pool shock works best with a balanced pH. If your pool's pH is too high or too low, the shock won't be effective. Ideally, your pool's pH should be close to neutral, around 7.2-7.4, before shocking.
Chlorine is still one of the most effective killers of algae so doing a super-chlorination of 10-20 ppm of chlorine can go a long way towards wiping out the algae. Liquid chlorine is an ideal shock for algae because it is fast acting and does not add cyanuric acid (CYA) or calcium to the water.
It may take a couple of days for the debris to disappear completely, so make sure your pump runs for at least 24 hours for the best results. If you have very cloudy water, use a pool flocculant. Both clarifiers and flocculants bind microparticles into larger particles.
The primary reason behind a green pool post-shock is often inadequate chlorine levels. Shocking is a method to boost chlorine levels rapidly to eliminate bacteria and algae. However, if the chlorine isn't sufficient, it won't effectively combat the algae, leading to a pool still green after shock.
Green pool water is often a result of algae growth, and chlorine is effective in killing algae and restoring the pool's clarity. However, simply adding chlorine may not be sufficient; you may also need to adjust the pH level, shock the pool, and run the filtration system consistently to fully clear the water.
Determine how severe the algae or other biological growth is. For heavy soiling, dilute 2 parts water to 1 part GK Greener Kleener. For light to medium soiling dilute 3 parts water to 1 part GK Greener Kleener. Easily apply the formula to the affected area using a garden sprayer or a brush.
