Safe to swim question

[LoneWolfArcher]

With my CYA at 120 (I have been managing well!), my FC target is at 9. My SLAM target is 47.

TFP says that for swimming you must be able to see the bottom of the deep end (my water is CRYSTAL CLEAR!), and FC needs to be higher than target, but lower than SLAM.

Is it really safe to swim up to 47ppm FC?

Yes. Because all the CYA is buffering the chlorine.

To add. If you really were at 47ppm, your water would STILL be less damaging to your skin, hair, and suits than going to a public indoor pool with a FC of 1ppm and a CYA of 0.

Also note that with a CYA of 120ppm, the minimum FC is 9ppm, that is not your target. You should be targeting about 12ppm for each daily dose.

Thanks. That is what I was thinking but 47 seems so high.

Also, I would rather error on the side of caution and stay closer to 20 than 9. I do not want any algae to return!

Keep in mind the CYA test isn't completely accurate and I'm assuming you did the diluted test to get the 120 - so it may be more like 100, may be closer to 140. Hard to say when the levels are higher.
