Once I discovered the pool store was incorrectly telling me my chlorine levels were high when indeed they were very low, the battle between me and the pool began. Here are my current test results:
FC - .70ppm
Combined Chlorine - .97 ppm
pH - 7.1
TA - 110
CYA - 83
Yesterday I added 32oz by volume of soda ash to increase the pH based on poolcalculator.com. 4 hours later I tested at 7.4 pH. Now my pH is down to 7.1 again. No major storm overnight.
Last night I added 7 lbs of 65% cal-hypo shock to try to get the FC up to about 20 and eliminate the CC. Prior to shocking the FC was 0.11 and CC of .43. The shocks seems to have done very little from my testing this morning (above). What's up?!!
BTW, the pool store told me my total and FC were at 5 last week when indeed the total was near 5 and the FC was below 1!! So I have managed to bring the CC down substantially but cannot get it near zero with good FC levels.
