My sister is struggling to get her pool set up properly and unfortunately since I am CL based, I am a bit clueless on where to start with the SWG. Here are the details:

Test Kit = Taylor K2005

Pool size = 15k gal

SWG = AquaPure 1400 + @80%. Pool runs for 8hrs from 11am to 7pm.

FC = 2

pH = 8

TA = 120

CYA = 60

Her PB installed the SWG turned it on and pretty much left without giving them much info on how to get it tweaked correctly. Right now, she is trying to get her FC up to 7ish and her pH down a bit so that she can determine here FC consumption. Last night about 5pm they turned on the SWG "boost" mode for a few hours right after reading the test results above and added 2 qt of acid (need to confirm strength). This morning, FC = 2 and pH still at 8. She went ahead and tried the FC and pH tests with the Aqua Check strips the PB gave her and they showed FC = 3-4 and pH = 7.8. My first advice was don't use the sticks....

She did say that her FC = 0 a few days ago, so that complicates things. Here is my thought:

1. Buy a DPD FAS.

2. Lower pH to 7.2

3. SLAM since her FC went to 0. I assume she can add liquid chlorine with the SWG, correct?

4. Increase CYA to 70-80

5. Determine FC consumption. What is the best way to do this? Ensure FC is above 7, measure FC in the morning and then in evening, and simply subtract?

6. Determine pool turnover time based on 15000 gal running VS pump at about 1750 rpm (Jandy default Pool speed for filtration).

7. Use TFP SWG calculator to get SWG %.

Lastly, when should the SWG run? It seems like it would be best to run it over night.
