Long Siphon Tube
I'm replacing my sump with with a sump/refugium and as long as I am doing this, I'm also going to hardpipe my overflow & return lines.
I'd like to modify my external overflow box to hang at the bottom of the tank, but still higher than the sump. This is to to hide the box and muffle sound behind a chair. My aquarium is used as a 3-sided room divider. I'd like to keep the box as opposed to a standpipe for mechanical filtration.
This means that the siphon tube will have to be longer, creating more head pressure in the overflow box. Does anyone see a problem with this? Will I get too much overflow? Has anyone ever done this?
I can make a drawing, if that would explain things better. Thanks.
