using pool with high fc level

[donniespool]

I am in the slam process at the current time and am not interested in jumping in the 'off green monster'..but as I return to something close to normal, what is a safe level of fc to swim in? I believe I read somewhere that it was fairly high if you did not care about your suit...thanks

Better than that. It is safe to swim in your pool at lower than SLAM value. We have yet to hear of a report of faded suits following this guide.

The original "Ben's Best Guess* Guide to Swimming Pool Chlorine" states that up to 25/30ppm "are generally harmless to naked swimmers, but can be quite damaging to swim suits. True competition suits, all polyester or all nylon suits are resistant. Very expensive fashion suits are NOT resistant!"

I'm not sure I would have an enjoyable swim at that level. I'm still working on getting my CYA down so I have to run higher chlorine levels and I have no problems in the 15+ range. As a matter of fact it's 14 now and I just got out....

thanks for the info

Remember, that best guess guide was also dependent on CYA. FC of 30 wouldn't be an issue if CYA was at 150 (I hope no one here intentionally has CYA that high....).

Besides FC being below shock, the pool needs to be clear enough to see the bottom. You need to see a swimmer if they go under.

The level of active chlorine at shock level is roughly 10x higher so swimming at that level can be considered the equivalent of swimming for 10 days instead of 1. It's equivalent to swimming in a pool with around 0.6 ppm FC with no CYA. So if you swam in this for a full season, you might notice degradation. My wife swam in a community center indoor pool with 1-2 ppm FC with no CYA and her swimsuits got shot (elasticity wore out) after just one winter season. In our own pool, she's gone 7 years of summer seasons before seeing such issues. Of course, it does depend on the quality of the swimsuit.

Umm... yeah.. certainly not me at a CYA of 200 from the previous owner using Chlorbrite for 4 years and we are in a stage 2 drought that has had me put off a 70% drain and fill....
