Hi All, 1st time posting
We opened up our pool a few days ago and put 3 gal. of liquid shock and added (6) 3" chlorine jumbo tablets in the chlorinator; no FC reading. Our pool water is crystal clear. The next day we added 2 lbs of granular shock through the skimmer and still no chlorine reading using our test strips. On day 3 we took for a reading at the pool store & was advised to add another 2 lbs of granular shock; still no chlorine reading. We have a 15,000 Gal (24' Round) AG pool (Vinyl), sand filter, using a 1.5 HP Waterway motor. Out of curiosity I tested the water coming out of the backwash and had a very high chlorine reading on the test strip. However when I test the pool water, I get nothing Would also like to mention that the pool is in direct sunlight.
Here are the results from the pool store:
FC = 0.14 ppm
PH = 7.5
TA = 113 ppm
CH = 170 ppm
CYA = 48 ppm
Can someone please help me get a chlorine reading in this pool?
