Use Pool Shock To Get Rid Of That Ugly Green Pool Water

Prevention is always better than cure. So in the ideal world you would never allow your pool water to become green and murky with algae blooms. But we live in the real world, and sometimes these things happen. So in this article we set out three basic steps to return your pool to a sparkling, clean and safe swimming environment.

First remove any debris from the pool. In particular any leaves that may be floating on the surface of the pool water or have sunk to the floor. Also check your skimmers and filter and remove any litter. If there are any pool floats or other accessories in the pool, remove these.

Check that pH levels of the pool. Pool shock treatments (the next step) work best within 7.2 – 7.4pH range.

If you decide to use a non chlorine liquid pool shock, choose a product with a high percentage of available Potassium Momopersulphate (MPH), the active ingredient in this form of treatment.

Calculate the appropriate dosage following the manufactures instructions. You will normally need to know your combined liquid chlorine reading and the size of the pool in gallons to work this out. But if in doubt add more shock rather than less. Shock treatment is an all or nothing procedure. You have to bring the pool to breakpoint chlorination point and beyond. Of course remember that you will not be able to use the pool until the free chlorine has returned to safe levels.

Keep your filtration system running throughout the procedure to help mix the pool shock treatment evenly across the entire pool. Remember to periodically backwash the filter to avoid it clogging up.
