I went away on vacation for a week and ran my SWG 2 hours each day. I had found for my size pool that was good for a correct reading FC reading.
When I returned, the color tested almost orange using the Basic test kit (K-1000). I decided not to run the SWG for a day or two to allow the level to come back to reality.
Over the course of the next week, I tested the water daily with the basic kit. Each day, the chlorine level tested high (in 5 10 range, at the top color level) but it had returned to yellow from orange. It was just very bright yellow.
Well, it's been almost a week since I have run the SWG and I am still getting consistently high FC readings using the basic kit. Do I simply have amazing CYA or what?
I will say the summer has been cooler, with the pool only in the 72-75 degree level and the solar cover on most of the time. Not alot of swimming here in West Michigan this summer.
So, I finally decided to break out the TF-100 and see what I could see.
Here are my results:
FC 2.0!!! (How can that be?!)
CC 1.5 (Mine usually is around .5)
pH 7.2 (ish)-maybe just a bit higher like 7.3-7.4 but this isn't a choice on the measuring instrument
CH 100 (vinyl pool)
Salt: 3,520ppm-just a bit above what is recommended
So, I am confused. My FC with the K-1000 is showing high chlorine consistently yet the TF-100 actually came up low. I don't want to go ahead and run the SWG and see "orange" again with the K-1000!
