In my opinion I wouldn't use that liquid tight conduit. It's just a raceway for wires. Its designed to keep water out, not hold it in. The manufacturing process uses oil to form the metal inside to provide mechanical protection for the wires.

Plumbing trial #1
Bought an Eheim 1048 (158 gph) and tried out the plumbing. The first thing I found is that my check valve is cutting the flow in half. The Reef Central calculator I was using refers to a swing-type check valve. The valve I have has a rubber disc which is pushed by water pressure so the water can flow around, and contributes significantly to head loss.
Even without the check valve, the Eheim is adequate for circulation but doesn't contribute much to flow. So I'll be trading in the Eheim for a Mag 3 unless anyone can tell me where to buy a Quietone 1200 or assure me that the Rio 1100 is not crap. Saltysurfer, are you sure about the Liquidtight? It looks like a white PVC core with grey coating (nylon??) inside and out. Should keep water in as well as out. Definitely not metallic--requires a ground wire for electrical applications. I would prefer something a little more flexible, though. Regards, Nevin

Pump and check valve
Traded in the Eheim 1048 for a 1250, which is just right at 300GPH. Still need a swing check valve for 3/4" PVC (thread or slip) if anyone knows where to get one...
Slow progress on the stand, but I'll have to get moving on it if I want to get the tank set up. The curved piece for the front, which I made by laminating 6 plies of oak veneer, is too flimsy. Currently I'm trying to glue some thicker strips of oak on the back. Hope it works! Regards, Nevin

Stand is done!
My progress has been very gradual and it's too long since I updated. My stand is done! Well, almost--have to build the light fixture. The bowfront tank presented a real challenge in adapting the stand. The curved front piece is made from 9 separate strips of wood glued together and even though the front layer of veneer bubbled up a little I'm more than happy with the final results.
I found a swing check valve at Ocean Aquatics and I think I have everything I need to plumb it. Oops, except for the sump which broke. The stand:  Close-up of the top:  That's all for now. Hope I can move along a little faster and update soon. Regards, Nevin

Here are a couple of pics with the tank on the stand and plumbing in place. I haven't put water in it yet. Hope it works!
Tank on stand:  Plumbing (warning: it's not pretty!):  I just bought another 5.5G sump. Regards, Nevin
