Gravity feed refugium from main tank, or pump feed from sump?
Which do you think is better? You save energy by doing a gravity feed from the display tank, but I'd imagine you'd get a large build up of detritus over time. I'm considering T-ing off the return pump in the hopes of reducing detritus build up in the fuge. I'd get a Super Dart if I decide to go this route. Regular Dart if I gravity feed. Difference of about 10-20 watts.
