No, actually this was a few years ago and the Canucks WON!!! I've only been to a handful of games, but they've actually won every game I've attended over the last decade or so. This wasn't true in the 80s or 90s though.

Rich,

it was only a 34g RSM, so much smaller than the OP's reef tank. I never had much luck with that tank and tore it down and replaced it with my 93g cube after this incident. I lost a med. Marine betta, a Naoko fairy wrasse and a third fish I cannot remember now. It was a complete Brain-fart moment and I still feel bad that my carelessness lead to their needless deaths. I admit I was really shocked that they died in such a short period of time without circulation. Before this happened, I would have sworn a tank could go half a day without power without suffering any casualties (unless overstocked like my main reef tanks usually are). The third fish may have been a mandarin goby. My leopard and yellow canary wrasses survived, but they hid in the sand for another day or so. I was in the process of planning a switch over to a bigger tank and had just recently added the MB in anticipation of that upgrade. My theory is the water change dropped the tank's ORP and without turning on my powerbar, the oxygen level dropped quickly. The 2 wrasses survived probably because they are used to surviving on lower oxygen levels when they bury themselves in the sand every night. As long as the pumps were working, this bioload was fine but without circulation it was clearly too much for the available dissolved oxygen levels in that size tank (4 small fish & 1 med.).

I had done a 10g water change and did another 10g change when I came home from the game.

Now I own 3 battery operated air pumps, a generator and a battery back up (UPS) in case of blackouts to ensure that I can at least keep my tanks oxygenated. I also check every piece of equipment after each water change to make sure everything is plugged in and working again.
