Vacation, Evaporation, and Specific Gravity Rise

[codered]

I'm going on vacation for ten days, but I'm worried about my 12g Nano Cube Deluxe.
I only have snails and liverock in it, so if something went wrong, its not a tragic loss (wish not to put my damsel in distress, I returned it to the LFS for store credit). But I'd still like to keep the progress I've made so far in getting it cycled, etc.
What is the best way to deal with evaporation? Will it be that big of an issue through the ten days? Here's what I plan to do:
I've taken the S/G down to about 1.021... that gives it plenty of room to slowly creep up. I'm taking my lights down to five or six hours per day, and I'm going to lower the temperature to 78 from about 80.
Should I do anything else? I can't find a ATO in time.

just a thought but if you know about how much evaporates each day i would think you could just set it up like a calk water drip. A gallon jug on a shelf above the tank and some airhose dripping more water into the tank.

That is a brillant idea. You get a star for today

The water level in a JBG 12 would have to drop like 3 inches before the filter stopped running. With your salinity that low, I wouldn't worry. My 12g almost never needs topping off. It loses like a half inch a week. The lids seal pretty tight.
