Ok, I apologize for the long wait for the pictures. Camera issues held me back a bit but it is all fixed now. I have 4 pictures to show the different views of the fuge. Please excuse the salt creep...
Picture 1: Fugetop view - The fugefeed line is on the left hand side. The 10G tank is drilled with a 1" bulkhead. Loc-Line has been fitted to the bulkhead and bent upward a bit. This was done to prevent the starfish I was a temp home for from flooding the fuge (again). you could use loc-line or a threaded strainer but all I had on hand was loc-line. The drain is a short 1" PVC section to a 45 fitting. Another pvc section was used to bring the output just under the water level of the skimmer section of the sump.
Picture 2: Fuge Drain - Better picture of the drain fittings.
Picture 3: Sump and Fuge Supply Lines (Tank drain line) - This design was done to allow full unrestricted flow to the sump while allowing very slow flow to the fuge. The bottom drain had to be used for the fuge to prevent all the water from just going to the sump.
Picture 4: Fuge / Sump Side View - Shows the raised fuge to allow the foolproof gravity drain method. No pumps to fail and has only been flooded once (dang starfish). The sump is sitting directly on the floor. The fuge is raised on a 2X4 frame approximately 5 inches higher than the sump.
A few things to note:
1. a strainer or loc-line is highly recommended for the drain to prevent flooding and chaeto from entering the sump sections
2. 10G tanks crack easily so drill VERY SLOWLY. Good thing they are cheap as we cracked 2 tanks trying to make this fuge.
Let me know if you have any questions or would like a better picture of a different area of the fuge
