Consider boosting your pH as well. I came back after two weeks to a clear pool but my pH was at 6.8 and my CYA went from 30 to the 60's. I had four floaters open full wide! It took 4 boxes of Borax to get the pH normal.

What I do is put out one jug of bleach for every other day. (I actually use LC, but I fill the jugs half with tap water first. I leave instructions that one jug is to be poured in the skimmer every other day. If we leave on a Saturday, I have my FIL do it starting Monday. It's basically 6 or 7 times. If you have a neighboring kid, he might want to make an easy $10 every other day just dumping the bleach in for you.

You could also put in a whole quart of Polyquat in advance. After 48 hours, you'll need to boost your pool's FC again. Then boost it shock level, and, if you have a cover, cover it, and use your chlorinator. But be ready to shock it ASAP when you get home.
