Vacation for 5 days - how to project FC loss

[lmleonard]

I recently learned the hard way that FC loss is not linear or constant. At a target FC of 5 ppm, I was losing about 2-3 ppm per day, so I thought that for a 5 day vacation, adding 3x5=15 ppm would be plenty of chlorine. But it was not enough and I got lots of algae.

I read some posts and learned that FC loss is closer to a percentage of FC. It looks like my loss is around 50% per day. So for another upcoming vacation of 5 days, I am thinking it will be impossible/impractical to add enough liquid bleach alone. What do you suggest I add? I do have some trichlor pucks, but the floater always gets stuck on the ladder. I am thinking of somehow tying up the floater so it has some room to roam but does not reach the ladder. I do not have a cover. Any suggestions? Thanks!

FC 5.0
CC 0.0
pH 7.5
TA 80
CH 60
CYA 40

That's what I would do.....unless you can have someone stop by and throw some bleach in for you. That's where an SWG or a Liquidator would be handy. You do have some wiggle room on your CYA. You may even benefit if it gets closer to 50.

do that and you'll be fine, especially if you can have someone just stop by only once midweek and dumpa couple gallons of bleach in for you.
