I just opening my pool yesterday, 06/27/10 and of course the water is very green with algae floating around on top of the water and stuck to the side of my vinyl liner. A little information about my pool:
1) 18 X 36
2) 30,000 gallons
3) Hayward Filer DE2420
4) Hayward pump - Not sure on the model just know it is self priming
5) I havn't taken any chemical readings yet.
Once I got the filter and pump working, I added 6 gallons of bleach and 3 packets of shock. The filter pressure value is usally sitting between 15 and 20, once it gets to about 25 I backwash. I had to backwash at least 4 times yesterady between the hours of 11:00 am and 09:00 pm.
The water doesnt look any clear, so I need to know if I need to do anything besides shocking the pool ? Also do I need to shock the pool after every backwash ?
