An up and running 375gal display
tank, with water sand, rocks, etc.
can weigh in excess of 5000 lbs.
That weight has to supported safely
and solidly, without the possibility
of vibration, tipping, etc. For
a tank this large, building a stand
out of wood is possible, but the
dimensions of the lumber that would
have to be used would cause the
structure to be so massive that
very little room would remain, beneath
the tank, for the needed sump and
other equipment, such as pumps.
For this reason, I decided to go
with a steel stand. Such a stand
can be built very stability out
of 1-1/2" square steel tubing. Properly
designed, to include sufficient
bracing, such a stand is rock solid
and the compactness of the steel
tubing leaves plenty of room, within
the frame, to work with.
As I know very little about welding,
I had the stand made, according
to my specifications, by a local
fellow, Jeff Robinson of JR Fabrications.
Jeff did a great job! I'm really
pleased with how the stand turned
out. As mentioned, above, it's made
of 1-1/2" Sq. steel tubing.
Here's a pic of the raw material
already cut to size:
Here, the welding of the pieces
comprising the base is completed:
In the next pic, the basic frame
is done. Just the bracing, for lateral
stiffness needs to be added:
Here it is, all framed up! All
the braces will ensure that it is
"torsionally" up to snuff.
And a quick pic from the end.
Braces here too. Notice the overhang
of the upper surface, to the right.
That overhang will fit into the
cutout in the wall where the tank
will sit. You can see that better
in a couple of later pics.:
All that needs to be done now
is to have the stand powder coated
a nice white color. That will ensure
that all the saltwater splashing
around the fish room won't be able
to coax the stand into rusting.
Here's the stand in its final
position, in the fish room. You can
see dark shadows under the bottom
of some portions of the stand. That
is where it is not touching the
floor. When the house was built,
the fellas that did the slab weren't
in a good mood. I'm going to have
to do a lot of leveling...
And a bit closer:
I had little flanges welded on
so that I can fasten the plywood
sheet that will cover the stand:
And finally, here you can see
how the stands fits into the wall
