In closing, I will need about 3 gallons of chlorine (12.5%) to get my pool to SLAM level. (I'm at about 6 FC now and three gallons will take me to 28 per the calculator. My cya is 70.)
The pool store sells a case of 4 gallons for $14. If I have to open the 4th gallon to get up to SLAM level, is there any harm in just pouring the rest of the gallon in the pool? A full gallon should add about 7 FC so I might be as high as 35 at that point. Is that a problem at closing time?
If I don't use the full gallon, or, if I don't open it, will it be fine to hold it over the winter?
Note - not planning on using Polyquat or any algicide.
