Having a hard time figuring this out........
My SWG claims a production rate of 1.38 lbs. per day. ( I assume this means when the dial is set to 100%)
I've had good success running my pump 10 hours per day with the SWG set at 50%. So I did some math.......
1.38 lbs./day = 22 oz./day of chlorine gas (this is the term used in the PoolMath calculator)
So, according to PoolMath, 22 oz. Chlorine gas/day should raise FC by 7ppm each day if I run the unit at 100%
Now, back to what I actually do....run 10 hours at 50% output.
10 hours @ 100% should produce about 9.2 oz of chlorine gas
Therefor 10 hours @ 50% should produce 4.6 oz of chlorine gas
According to PoolMath, 4.6 oz of chlorine gas should raise the FC by a little less than 1.5ppm.
However, I'm pretty sure I have more than 1.5 FC loss each day as I measured it (without the SWG turned on) to be closer to 2.5 - 3.0 FC loss per day. But the 50% setting seems to be maintaining my FC at around 7.0ppm over the last several days.
Can anyone point out where my math or any assumptions I use are incorrect?
