Safe to swim with high FC

[SHOTS]

That is very sad.

We are at the very end of our SLAM. Our water has been perfect all year, but we let it slip last week when we had 5 days of rain. It got a slight green tint so we started the SLAM. We can see the bottom and it looks pretty good, just a little cloudy. The kids are begging to swim today, but the FC is 15 (our CYA is 30-40). Is it safe to let them swim with the FC that high or should I make them wait until the FC drops?


This was split off the topic here:. This is why we say

An FC level of 15 will not hurt them but have you done the OCLT to make sure the problem is solved completely before you conclude the SLAM process.

Yes, last night it only dropped .5. Do you think that is sufficient to let them swim? I was going to maintain an FC of 15 for another day or so just to be safe.

If it is safe to swim depends on your CYA level. If the FC is below shock level for your CYA, then yes, it's safe to swim.

Right, it is safe to swim when your chlorine level is above the minimum and below the shock level for your CYA on the Chlorine CYA Chart
