Hi all. This is my third summer on a new pool. I started getting ready to open my pool a few weeks ago. So I started my heater and then ran through the full range of tests (25K gallons):
I shocked the pool and everything seemed fine (BBB 6%). No problems holding my chlorine level. The TA was a little low so I added some acid and then a few hours later I added some baking soda. This clouded the pool as I expected and was still cloudy the next day. I tested the TA and it was at 90 and the PH was 7.5. I then treated with polyquat.
The next day my chlorine had gone to zero. I threw in the robot and removed any remaining debris . The pool was still so cloudy I can't see the main drains. The pool walls are clean, no visible algae growth anywhere (no mustard), no debris. Backwashed before first shock and sand was clean.
I started to shock again today. I have been doing it all day and I literally can not continue with the shock because I ran out of chlorine after having depleted both Sam's club and Lowe's. I have added 32 gallons of 6% today alone. I think I had the FC up to 23 at one point. It literally drops 10 points within 2 hours. At one point I think my FC was 15 and CC was 1! I added my last 4 gallons about an hour ago. FC was at 11. 4 gallons should have taken it to 21. Measured 2 hours later and FC is 16. There is something wrong. I even swept around and checked for dead birds, squirrels, etc. After looking back at the Polyquat bottle I think I may have treated with a 40% thinking I had the 10% so I may have added way too much.
Any ideas or help would be appreciated.
I'm waiting for the FBI to show up at my door. When I went back the second time for another 15 gallons of Chlorine to the same cashier she started giving me funny looks and then got on the phone and whispered something.
