How to Clear a Green Swimming Pool
Nothing can be as heartbreaking as pulling your pool cover back to find the water turned green and swampy. Such an occurrence is an indication that algae have taken over the water and it needs to be thoroughly cleaned and treated before anyone can swim in the pool. Below is a step-by-step guide on how to clean a green swimming pool.
- Prepare to Treat the Swimming Pool
Start by testing your pool water using a chemical kit to check the pH and chlorine levels to ascertain the degree of the issue. Pool water turns green due to the growth of algae which occurs when the chlorine level is below 1 mg/L. The best way to destroy the algae and get the water back to normal chlorine levels is by “shocking” it with chemicals.
Another practice that prevents algae from forming in your pool is correct pool maintenance, this can involve getting functional filters and ensuring that the water’s pH level is steady throughout. Algae grow constantly and allowing your pool to stay without proper swimming pool services even for a few days can make the water go green.
- Stabilize the Pool Chemistry
It is crucial to balance the water pH by putting a base or an acid to get the pH level to about 7.8. This level is best when you want a higher range for your pool water and it is also necessary when treating the pool for algae. To balance the pH level of your pool;
- Switch the pump on so that the chemicals spread throughout the swimming pool.
- To adjust the pH level, you can increase it using sodium carbonate or decrease it using sodium bisulfate.
- Ensure that the Filter is Functional
Get rid of any sticks, leaves, papers, and other waste that could be blocking the filter. You can backwash it as well and ensure it is working properly before adding reagents to the pool to destroy the algae. You will need to have the filter running throughout daily so it filtrates all the algae when cleaning the pool.
- Scrub Every Part of the Pool
Using a pool brush, scrub the pool thoroughly before you put any chemicals in the water. Algae stick on the surfaces of the pool and hence scrubbing it is a sure way to get rid of it. Scrubbing also breaks it up and enables the chemicals to work efficiently.
To clean the pool thoroughly, scrub the parts where algae buildup is visible to break it up. Remember to take further care of your pool by minding the material used on your swimming pool installation. For instance, if the swimming pool is made of vinyl, scrub it using a nylon brush since wire brushes can destroy it. Nevertheless, a wire brush works well on a plaster pool.
You can then “shock” the pool using a high concentration of chlorine to eliminate the algae and disinfect the pool. If the algae in your pool are too much, you might have to treat it severally to stop it from growing further.
