What to do with extra chlorine?

[Saturn94]

Our pool pump motor was out of commission for a few days (needed new capacitor), so I bought some 10% liquid chlorine to keep FC up until we could fix the motor and restart the SWCG.

The motor is up and running now.

I still have 3.5 gallons of the chlorine left (date code 20 125). Am I better off continuing to manually chlorinate to use it up while it’s still about full strength, or keep it until I need it at closing in mid October, knowing it will have lost some strength (stored in garage, not climate controlled)?

What would you do?

Thanks.

I'd keep it, and use PoolMath to back calculate the strength in October. You do that by adding a known amt of chlorine, test to see what your FC is after 30 min, and adjust the strength of your chlorine til you get the amt you added.

I also had a partial bottle of 8.25% (about 100 ounces, date code 19 225) left over from last Oct closing that I put in the pool the other day. Based on the FC rise, it appeared to have degraded to about 6%. I was surprised it hadn’t degraded more than that.

BTW, having to manually chlorinate the past few days sucked. The SWCG has spoiled me and made me lazy, lol!
