Last year, with the help of this forum, I took control of my pool, and bought the Taylor K-2006 FAS/DPD test kit. I stopped going the the pool store and began using liquid chlorine (12.5%) as my sanitizer after having major issues with algae during pool opening. BBB method worked well for me, so I was looking forward to an easier opening this year. On June 4, pool opened with water green and FC 0, pH 7.8, TA 90, CH 170. I ran out of the CYA test, so could not determine exact amount of shock to add to SLAM. Blindly added a few jugs of liquid chlorine, and the pool cleared up within a few days. Brought water sample to Leslie's so I could have CYA tested until my new bottle arrived, and they told me it was 70 (which I thought was low considering it was at least 100 at closing, and we did not drain the pool). So I based my SLAM level on CYA 70, and SLAM target was FC 28. I followed the Pool Math instructions religiously, and water stayed crystal clear, but did not pass OCLT. Hubby convinced me things looked good, and we stopped running filter 24/7, but within 2 days, pool got cloudy again. Had to SLAM again, hubby added algaecide and after a few days, water became crystal clear, but still failing OCLT (anywhere from 4-10). Have been brushing every day, using Aquabot as well to get the the bottom of pool, constantly adding chlorine to maintain FC 28-30. Tried to test pH, but results turn purple due to high FC.
By then, my own CYA test arrived, and I got a reading of 90, so I assumed I failed OCLT because I missed SLAM target. For the past few days, I have been raising my FC target but have been unable to pass the OCLT. Here are my FC readings:
6/15 - during the day tested FC 35-38. Tested at sundown FC 27.5. Added 199 oz chlorine to raise FC 39.5
6/16 - 7 am reading FC 35.5, added 1 gallon to raise FC to 43. 11 am FC 39.5, added 96 oz to raise FC 45. 3:45 pm FC down to 35. Added 2 more gallons to target FC 50. 8:30 pm FC 46. Added 48 oz to bring up to FC 49
6/17 - 7 am FC 42.5.
Water is still crystal clear. Hubby is suggesting we just let FC level go down so we can swim and enjoy it, especially for Father's day tomorrow. I am ready to give in because it is so beautiful out, and pool looks so inviting, and I am tired of adding all this chlorine with no results.
Why am I still failing OCLT despite having such high FC levels that exceed the target for my CYA level? I have repeated the CYA test multiple times, but am pretty sure it is at 90.
Are my FC levels now too high to swim in the pool?
Please Help!
