Chlorine or SWG Super Chlorinate to SLAM?

[Scotland]

Lets say I have a big pool party tonight (I wish) and decide to SLAM the pool tomorrow.
Am I best using chlorine, or the super chlorinate feature of the SWG?

When we have our family reunion, which usually results on about 15 kids in the pool, I increase FC level to the top end of the CYA/FC range with chlorine. Usually do this about 2 or 3 hours before I think the pool is going to be used.

Will also measure the level after everyone leaves and use more chlorine to bring back to, or just above, the recommended target.

If you have it I would say use the chlorine, and if you can add before you have the party.

I have found using liquid chlorine the fastest way to boost levels after a party. I tried using SWG one time, but the level wasn't increasing fast enough for me to feel comfortable with it. 1 or 2 cups of 10% chlorine and that was all it took to boost it quickly and make the water clear again. So now I keep a jug handy for the times when we have a lot of people going swimming. @-MacGyver- 's idea of adding before is a good idea I might try as usually after a few hours with a lot of people swimming, the pool starts having a haze.

For large pool parties, our recommendation is to raise your FC to 20% of CYA before the start, call a time out mid way (potty break) and test and add more LC if necessary, and then test afterward.

You could raise your FC using the SWCG if you like prior. But liquid chlorine is more exacting and immediate.

So just verifying. For CYA 70, I need to raise FC to 10 or 14?

20% of 70 CYA is 14 ppm ..

That is just a recommendation. Your pool may vary.

Do you add back to the 20% of cya at halftime of the pool party? At the conclusion of the party do you add to 20% again or just to the top of the fc/cya recommendation?

Maintain your FC based on the FC/CYA Levels
