i woke up this morning to the worst sound imaginable for an aquarist - silence. My entire house power was off!! I immediately ran to the tanks and found out from my light timers that the power tripped at 3am, because water had got on my power board for the 46g. Many expletives followed this discovery. I checked the tank and found no leaks, but a very wet carpet. I still can't figure out why. The ruined power board was immediately removed, I plugged everythingt into a spare powr board and put the new board on a window ledge. The power was out for 4.5 hours. I can only pray that both of my wet/dry filters maintained enough moisture to protect the bb. I have to leave in 20 minutes for my Easter trip, and won't return until Monday evening. Could anything else POSSIBLY go wrong this week?! No casualties overnight, and the temp in the tanks dropped from about 28-9 to about 23-4. I have done all I can to make sure the tanks will continue to run in my absense, but can do nothing for any ammonia spikes. Water changes were completed last night, and all tests were 0,0,10.
