Holidays. How long can the reef survive?

[BMW Rider]

With an auto top off and feeders, a week should not be unreasonable to leave the tank unattended. I too am going to be away for a week, and will have my tanks set up to be self sufficient during that time. I will do a water change on my FO tank before I leave, then the reef will be just due when I get home. Both have enough TO water to get by for at least a week. I use feeders to deliver a dried food mix once daily for the week. Not ideal, but will be better than starving. I am going to have my inlaws come by and check the house a couple of times and look at the tanks to make sure they are still running. No other work will be needed.

We were away for a week in January, and this routine worked fine then. Good layer af algae on the glass to clean off, but otherwise no ill effects.
