I am gradually adjusting my new SWG to maintain a constant FC. I figured that if the FC, TA, and CYA are constant over 24 hours then I am adding Chlorine as fast as the Sun etc is eating it, so I set about to calculate how much that was. (Log is in my profile)
The cell is rated at 1.45 pounds of Chlorine gas per day at full power. I am running it at 9% over 24 hours which gives me 0.131 pounds per day. The pool is 10,400 gallons which should weigh 10,400*8.33 pounds or 86,632 pounds. (That is not corrected for temperature, which is about 90 degrees) So if I have this right, Chlorine parts per million would then be 0.131/86632*1E6 or 1.52 ppm.
Surface area of the pool is 12x29 feet or 348 square feet and it gets direct Sun about 4-5 hours per day. Is 1.52 ppm a reasonable amount to be adding? (Side note - the energy going into the pool from the Sun is about 150 KWH per day, which is twice my house electricity consumption! Too bad I can't capture that.)
By having this number, I should be able to adjust the FC at a predictable rate knowing that 9% power => 1.52 ppm.
