This 20 gallon column style background was constructed entirely from
scrap pieces of styrofoam. With at least seven previous background
projects, the scrap collection was getting rather large.
Scrap pieces were stacked, then secured with bamboo skewers, then
shaped with a hot wire to create an impression of natural occurring
erosion.
As in previous projects, the aquarium was positioned on its back to
ease the application of cement between and behind the columns. With
this particular project, there's quite allot of cement applied directly to
glass. The liquid acrylic used in the cement mix helped insure a strong
bond to the glass.
This step is always satisfying since it hides all the "non-aesthetic"
aspects of the background.
As always, it's important to cover everything you don't want painted
including the bottom trim of the aquarium. Even painting black over a
black trim can later result in unwanted marks on furniture if, for
example, an old dresser or chest is used as an aquarium stand.
Flat black enamel paint has been applied here. One trick I sometimes
use is to tear small holes in the newspaper over each hardware
compartment and shine a light down inside to see any spots that may
need a little better paint coverage. This works best in a darkly lit room.
Once the aquarium is up and running, any areas around the hardware
compartments with thin paint may allow light thru which could be a
visual distraction.
Removing the paper template reveals the painted curve that follows the
edge of the background inside the glass.
Artificial Amazon Sword plants seemed to work best with this vertical
themed background.
Hidden in the shadows of the background are a heater on the left and
H.O.B style filter on the right. The filter returns water over the top of the
background for optimal water circulation.
This 20 gallon background was made almost entirely of scraps
of polystyrene left over from previous projects.
Having already completed more than a few of these
backgrounds, my scrap collection was getting a bit large. It
was a good feeling to recycle.
