Pull the media from the filter and hang it in the tank. that way as you manually move water around useing a net in a figure 8 motion (added benifit of removing small particles as well depending on how fine your net is) the filter media will have some water circulating around it. if you are using Efimech Pro (the plastic black stuff) bag it up otherwise you'll be fishing it out till christmass.Lost power three hours ago. How long before filter goes sour?
What's the recommended restart process?
