When doing water changes in an All-In-One aquarium with a built in filter, how long is it ok to leave the biological media out of the water ? The filter has a top and bottom intake.
 
60 minutes if it's not near a heat source or in sunlight.
That’s good !! It’s probably only out of the water for 10 minutes or so. It’s difficult to block up the intakes to hold enough water in the filter to keep it submerged
