I've been reporting on my success with the Intex SWG over in this thread: http://www.troublefreepool.com/viewt...hp?f=21&t=1090
To recap, I've had the SWG for a little over a week, been reading FC at 5+ (off the high end of the scale on DPD tester). Earlier this week, I finished adding borates to the pool, and just today received the FAS-DPD reagents and powder necessary to test higher and more accurate FC measurements. After testing my chlorine levels with the FAS-DPD method twice for accuracy, the levels seem a little bit high. These are my most recent numbers:
I'm kind of amazed that we haven't been experiencing more eye discomfort with this level of chlorine, and now that the borates are in the water, there is absolutely zero eye discomfort and the water has a new found clarity unlike anything I've ever seen in a pool. Just in case you're not familiar with the Intex SWG, it only has a digital timer that allows the number of running hours to be programmed between 1 and 12, but there is no way to adjust the percentage of electrolysis that takes place during the running hours. Once this is set, it will repeat the same cycle at the same time every day, but judging from the 11.2 FC reading I measured, it doesn't seem necessary for me to continue running the SWG for the manufacturer's recommended 12 hours for our 24' round pool.
As far as coming down from this current set of measurements, is it best to not run the SWG at all until the level comes down and then experiment with the run times, or should I just start running the SWG for less hours each day? Is there any danger in letting the kids swim while the FC is this high?
Thanks for all of the great help this forum has given me already!!
