Cleaning Green Merky Swimming Pool Water
One you need to shock the swimming pool with chlorine. We recommend getting granular chlorine (normally about $6 for 2lbs) and mixing it with clean water. It is a little cheaper than buying liquid shock. Put 2 tablespoons of glandular to one gallon of water and dissolve it and mix it. Spread around the pool, then run the swimming pool filter for 48 hours. If algae is present, use a copper algaecide to rid the swimming pool of the growth before shocking.
Over chlorination will not cause algae growth. Have the pool tested for phosphates. In many cases, this causes repeated algae growth. Then triple shock with 3L liquid chlorine per 10000L pool water. You have to add enough chlorine to kill all the algae and leave a bit of chlorine left over. Once the dead algae settles to the bottom, vacuum to rid the swimming pool of waste.
Very heavily shock the pool, depending on how many gallons your pool is, preferably using a good amount of liquid chlorine. Do that every other day until the algae is gone. Clean your filter at least twice a day if using a cartridge filter and backwash once a day if using a D.E. filter.
You can also re-filter the pool or have a swimming pool professional clean the swimming pool.
