Back from Vacation for over a week- kids want to swim tomorrow!?

[Kmeans]

Hi-
We were away for over a week with no one to tend to the pool. The filter didn’t run and there was no chlorine added during that time. We are back now and my kids want to swim tmrw! The pool is very clear, besides needing a good vacuum. Do we just need to add chlorine tonight and should be ok for tmrw? How much chlorine would you add?
Thanks!!

If pool is clear, I would raise to slam level this evening, swim tomorrow.

Thanks- I have been using the Taylor testing system- but am out of CYA fluid- it has held around 30 last time I checked it.
so raise chlorine to 12? Then it will be okay to swim with it that high?
Usually keep it around 4-6..
Any idea how much chlorine it would take to raise it to that level? Starting from probably zero!
thank you!

I guess I would test your FC before adding any. Then you have a choice as to whether to go up to SLAM level for your pool, or up to your normal level.

SLAM level would be safest, as your FC level may have dipped below minimum while you were away, and even though your pool is clear (you're lucky) algae may have developed in some places.

You can swim safely at SLAM level.

Question: Why did you not run your pump while away?

Thanks for your reply- we didn’t have anyone to come by and check on the pool and we didn’t feel comfortable leaving it running- plan was not to be gone as long as we were.

I have added quite a bit of chlorine- over a gallon ,and level is still 11
Trying to get to 12-
Is there something that could be causing it not to raise? Seems like I’m adding an awful lot and am debating adding more!
thanks

yes...algae or other contaminates.

1 gallon of chlorine should barely give you 3-4ppm in a 19,000 gal pool

Ooops, just checked... 1 gallon will give you 5ppm of FC it its 10% strength.
