How Long Does It Take For A Green Pool To Get Clear?
You will find an impressive transformation after 24 hours of chemicals and circulation. Your pool can no longer be green. However, it will remain cloudy for the next few days, necessitating a lot of brushing and filtration. There are likely to be a few stubborn isolated green areas that will need brushing.
If your pool is still green after 24 hours, it may be due to an abundance of the wrong chemicals, such as phosphate or cyanuric acid (“stabilizer”).
Chemical Criteria for Clear Pool Water at a Basic Level
To summarize, these are the chemical criteria for maintaining a clear pool.
Accurate pH level - The pH of your pool should be between 7.4 and 7.6 for regular use, and between 7.2 and 7.6 for surprising. Cloudiness is caused by shocking a pool with a pH that is too high.
Balanced Alkalinity - pH and chlorine levels are easier to manage when alkalinity (dissolved salts that hold pH stable) is in the right range.
Free chlorine - Algae will flourish and turn your pool green and cloudy if there isn't enough free chlorine throughout the water.
Why is the pool still green after it has been shocked?
If you use tablets to supply chlorine (such as Tri-Chlorine), the stabilizer in the tablets (cyanuric acid) will build up over time and “lock up” the free chlorine molecules (Cl2). Even if your test kit shows a very high chlorine reading, the chlorine is unable to kill algae because it is not in the correct chemical type.
Algae can be exacerbated by high phosphate levels. Phosphorus, or phosphate, can reach your pool by leaching from leaves or organic debris in the water, or by floating in from fertilizer sprayed around or around your pool. Algae feed on phosphates, so phosphorus-related algae blooms can be daunting during the summer months when the water temperature rises above 78–82° F. A phosphate-removing device, such as this one, can easily treat this condition.
Maintaining your pool in balance
Tips for keeping your pool in good shape:
Whether it's an in-line, floater, or salt system, make sure you have a reliable chlorinating system. Chlorine must always be present in the pool. It's not a smart idea to preserve the pool by tossing a jug of liquid in it once a week. A simple chlorine floater made from tablets is very powerful.
Make use of a water clarifier.
Make sure your filter is clean. By far the best filter to have is a DE filter. While they are initially more expensive, they will save you both time and money in the long run.
How often to clean your filter:
Backwash DE filters once a month.
Backwash sand filters every two weeks. If you don't backwash your sand filter for at least four minutes, you'll end up with dirty water shooting back into the tub.
Filters for cartridges: Clean it every three to four weeks, unless the pool has algae, in which case you can clean it more often. More information on how to clean a cartridge filter can be found here. Every three months, soak in trisodium phosphate.
