We have a 16x48 intex metal frame pool, we filled it last week and the water was crystal clear and at that time I put in maybe a cup of shock (from Wal-Mart). The water stayed clear for a few days and i have been putting tablets in the skimmer each day (1-2) and test everyday and never had a chlorine reading. So I started putting 6% bleach in everyday and we now have it in the 4 -6 range but the ph is high 7-8. But my biggest problem, I think, is the powdery substance on the bottom of the pool when distrubed is makes the water very cloudy and opaque. I run the pump 24/7 and clean the filter 2-3 times a day. What can I do...... HELP!!!
