Here's the story... our house has a very old circuit breaker setup and the original manufacturer is no longer in business. The problem with this is that the circuit breaker box and some of the breakers themselves are going bad and it is not possible to find replacement parts. So bottom line is that we going to get our circuit breaker box and breakers completely replaced with all new stuff. This obviously entails the power being off for several hours or maybe even a day. I won't know the complete details until the electrician shows up. In any case, how worried should I be getting? The tank has only been up for just over 5 weeks, but is completely cycled and has been "stable" for the last few weeks. The main reason for this is due to buying TBS live rock... so my cycle was relatively quick.
