The refugium is plumbed to the display. It used to be up higher at the apt. and drain by gravity to the DT, now it drains to the sump. This design causes less pods to enter the DT, but it seems to be cleaner than it used to be. We just moved it as it was, minus the water. The pipefish are actually opposite of what you see in the pics. The dragonface is in the fuge, I take her in & out of there as I see the pods increase/decrease. The african pipe is in the DT now, as she will eat mysis as well as pods. Thanks for all the kind words.
