Pools that turn green are dangerous and just plain gross. To get your pool clean follow these steps.
Step 1 (Green Pool)
- Add lots of chlorine. Get your chlorine level up to 10 ppm (parts per million)
- Check your conditioner level. It should be between 30-80 ppm
- Check to see if your filter needs to be cleaned (Not Back Washed).
- Brush down the entire pool
- Run the pump for about 8 hours
- Wait for tomorrow
- Repeat until the Algae settles at the bottom of the pool.
Step 2 (Pool with a bunch of algae settled at the bottom)
- Check your chlorine get it up to 5-10 ppm
- Backwash the filter (or clean it if it is a cartridge filter).
- Vacuum up all the algae to waste if possible. If not you just have to keep back washing or taking apart the filter and cleaning it until you get it all out.
- After it is vaccumed you need more circulation. So again backwash the filter and add a little DE (Sometimes at this point even back washing doesnt help. You may need to clean the filter again).
Step 3 (Clear Pool)
- Check your chlorine and keep it about 5 ppm
- Look at the water. If it is clear throw a party!
- Clean your filter again
- Keep your chlorine at 5 ppm
- Keep the conditioner level at 30-80 ppm
- Keep the PH between 7.2-7.8 (up to 8.2 on a salt pool)
If you noticed the theme here was Chlorine at 10 ppm and a clean filter. You need 3 things for clear water.
If you are missing 1 of the 3 you will have lots of problems. When your filter is dirty you lose both filtration and circulation. A clean filter will solve a lot of problems you may have.
