Power Outage

[kg221]

I just started my 90 gallon tank last night and I was curious if the power went out, how long could the system survive without circulation? With no stirring of the water or stiffening water and pouring it back in. If I am home I have sufficient means to providing power to my tank in the event the power goes out, but I if I am at work and not able to provide power I am curious how much time I have before things start dying off.

About 6 hours max if temp is pretty neutral seems to be rule of thumb. Really depends on bio-load though as larger faster fish will use up more oxygen.

My 120 was fine after 6 hours and I have a bluethroat trigger, two small tangs and a few other really small fish.

Thanks for the info. I wont have a big bio-load right now as I am starting the tank but later on it will definitely increase so I will keep that into consideration.
