Liquid Chlorine Usage Rate

It will make it last longer, yes....BUT....think of your FC throughout the day, it will be burning off all day with sun exposure slowly lowering. With the higher CYA the point where the chlorine stops working will be higher. So...let's say you go from 50 to 60 on CYA. Now your chlorine will go down 6ppm over 14 hours of sun exposure instead of 12. Problem is, now your chlorine level needs to stay above 7 instead of 6 to be effective. You may have gained a couple hours of 'life' but you're still using the gallon a day to keep the level a bit higher. Hope that makes sense. I agree with @Darin, save yourself a headache (high CYA) and get a SWG.

Yes. I think I will keep doing just the LC except when I go away for a week, I wilI raise my fc to 20 ppm with LC and will use the floaters (pucks)to keep it above low range till I get back. I will look into a swg. My pool had this disconnected (see pics). I think it’s a swg controller and the cell had been removed and capped. Not sure tho. Looks outdated…
