i have a powerhead that has a tubing attachment that draws air and puts oxygen in the water that helps more than you'd expect. i was without power for 10 hrs and not one loss. i've got some decent size fish and alot of them in my 210 gal. battery powered airator the kind you'd use in a live well works great too. you can get them pretty cheap and just get a 12v battery from walmart and you're in buisness.USMCtanker;1874423; said:not all died, but ya, no air or filtraion over night in both tanks = bad things
I am not an electrician, so this advice should be taken with a grain of salt.rallysman;1874838; said:Sounds like it was a GFI outlet. If that's the case be careful and keep an eye on it because defective equipment will trip it. The chance of all heaters kicking on at the same time is slim, but it could happen. It could have also been from a connection to ground that got loose or a simple water splash out of the tank.
Sorry for your loss Those were some beautiful fish.
