Liquid Chlorine
CYA currently at 50. Slamming and did recommended amount of liquid chlorine this morning. Calculator said FC needed to be 20. I added the chlorine and now my FC is 34. Not sure how that happened? Question is, my kids want to swim. Is that level unsafe? Do I need to do something to reduce it?
 
Best to not swim when the FC is above the SLAM level FC. The FC level should fall pretty quickly if you have organics in the water.

Be sure you can see the bottom of the deep end of the pool before anyone goes swimming.

I thought so. I can see the bottom but it’s still just a tad cloudy. I’ll hold them off for today lol. Thank you!

Make sure the chlorine percentage you’re using in poolmath is what you are actually using. Pool math says it’s 10%, but if you were using 12.5%, the FC would be higher than intended.
