I recently opened my in ground pool two weeks ago. The volume of the pool is approximately 20,000 gallons. The pool water has a greenish tint and the water appears cloudy. I have used a automatic robot to clean the bottom of the pool and clear out the debris settled down there. I have used a pool brush to scrub the walls / bottom of the pool in an effort to dislodge any debris. During all this time, the filter system was running on full. Chemistry of the pool as it stands right now:
- PH of 7.6
- total alkalinity of 90
- Free chlorine of 2 ppm
- combined chlorine of 3 ppm
- Calcium hardness of 220
I have already shock chlorinated the pool two days ago. I added dry acid to lower PH from an initial reading 8.1 and calcium chloride to raise dissolved calcium levels from an initial level of 150 ppm. The pool is a concrete pool with no liner.
What could be causing the greenish tint to the water and the cloudiness of the water?
