A power strip does help, as many others here have found out, if you set it up in a way that eliminates having to remember except for the obvious, it cuts the headaches.
Now I talk from that side of 50 where you have to start writing notes to yourself and everything......My first disaster with a water change was that I DIDN'T unplug the heater, so when the water got down it was running, and when the cooler water hit it, the heater shattered!!!

So your woops was much less of a problem. I'm glad the fish are OK.
