I have an intank overflow going from the top to the bottom of the tank and the water emptys out through the bottom of the tank through a drilled hole. I was thinking because of a space restriction that i could put a pipe in the whole where the water drains down to the sump that would make it so there is about a foot of water in thr overflow and make a regufugium in there so the tank water overflows into thr refugium then over the pipe down into the sump. Do you think this will work. What are the ups and downs to doing it this way? Thanks
