I've got two Aqua Clear 70 filters running on my 55 gal tank. When I do water changes all the water siphons out of the filters. I've tried to pour some tank water back in, but it just continues to siphon out. It takes me roughly 1/2 hour to do a 50% water change. Question is how long can the filter media with all the bacteria be sitting there with no water surrounding it before it starts to die off? Just want to make sure I don't need to do something different so I don't cause myself problems.
Thanks!
