Well it is a sad day today.
At 230 this morning I woke to silence. This is a bad thing since my 400g tank is in the room next to the bed room. I imeaditly got out of bed and checked the tank only to find my worse night mare.
A GFCI had tripped and my return pump and skimmer were not running. The silence was defining. As I turned on the lights and looked in the tank, there they were, my 2 naso tangs, pink tail trigger and Moorish idol, all upside down on the bottm dead. They had suficated due to lack of oxeygen. I do not know how long the pumps were off but it was long enough.
I got the pumps started again and crawled back into bed. I had a hard time going back to sleep. When I awoke at 5:30 to get ready for work, I finally went in to asses the damage. My female Naso was up and in the corner shaking but looked to be alive. I saw some of my other fish swiming as well.
However I did incure some losses:
12" 8 year old Male Naso tang
6" 8 year old Pink Tail Trigger
5" Gold Flake Angel
3" Rusty Angel
6" 4 year old Moorish Idol.
Yep, it's a sad day as they all were doing fine when I fed them yesterday afternoon. I have 3 different circuits that run my tank. All have GFCI outlets. I have had all three of them trip for no reason. The only cause I can think of is the salt humidity that is in the enclosure of the tank has caused enough corrision to cause them to trip. I am going to look into installing GFCI breakers and get rid of the GFCI outlets. I'm also going to look into keeping at least one of my closed loop circulation pumps on at night. I have been shutting them down for power comsumption as well as noise reasons. That may have to change.
