Here you can see the crack in the divider as I removed the original sump. Unfortunately I lost a lot of pods emptying the sump.

Here is the syphon drain into the sock, emergency drain and return plumbing and ATO. I do have some 3/4" braided tubing for when I replace the pump as 1" is too stiff.
Here is a look into the return section. Ideally this section should be about 3 times the size. Porous filter material breaks the water falling and eliminates microbubbles. I do have a problem with the ATO alarm going off occasionally due to the small return area volume.

Wow they are beautiful. Can they be problematic with Corals
You can see an unusual brown sponge just to the right of this small green toadstool mushroom.
