I am trying to design an electrical system that allows me to turn off all my water circulation devices for one hour, then automatically switches them back on once the hour has elapsed. (This would occur during feeding.)
The basic concept would be similar to this:

There would be two key differences from the above, however.
First, the device would need to be a traditional plug-in timer, rather than an in-wall unit like above. That way I could plug all the devices into the timer using a power strip. Second, the timer would need to keep the power off for 60 minutes, rather than keeping it on. All the timers like this that I've seen are designed to keep a set of lights running for an hour before automatically turning them off. I want the exact opposite: keep my circulation devices off for 60 minutes, before turning them on when the time is up.
Has anyone designed something like this? The basic idea is to twist a knob at feeding time to turn off all circulation, then have the circulation pop back on after 30 or 60 minutes. I'm trying to avoid situations where the refugium, skimmer, and canister are allowed to sit in hte off positions for long periods of time (i.e. when I forget).
