My husband built a sump for me with a 55 gal
tank according to plans I found online and it has been working quite well for about 2 months now Unfortunately it was before I had found a used skimmer to add to the sump The one I found requires a 10 x 15 space and mine is only 10 x 12. I am using the center for a refugium. So i have a stupid question - Is there any way to move that divider a few inches to allow enough room for this skimmer? I know I wouldn't be able to silicone it back in but if it is wedged in tight, could that work? Please don't kill me for asking a dumb question.
