Added 1 ppm FC over 7 hours w sun. Running pump all night with SWCG at 100%. Measure 12 hour production in morning. Should produce 3 ppm over 12 hours. Pool should consume only 1 ppm if no algae present. Expect 8.5 ppm in morning. Today in 8 hours 2 ppm produced. With 5 hours of sun. Used 1 ppm FC.

SWCG set to 70% targets stabilizing FC.
SWCG at 100% 14 hr pump runtime at 100% = 0.28ppm FC per hour or 3.92 ppm FC.
Last 24 hours we produced
.30 x 3.92=1.176 ppm
Yesterday’s reading of 10.5 + 1.176 = 12.26 ppm total
minus today’s reading -9.5 +12.26 = 2.76 FC used. Inferring we need to calculate x% of 3.92 = 2.76 . Or
2.76/3.92 =0.704 or 70% for the SWCG setting.

pH 1 drop = 7.7, 2 drops 7.5. Added 20 ounces and ran acid feeder for 30 minutes. Line was empty. Not sure length of time required to fill tube. In theory that would take pH to 7.5.
