This 20 gallon DIY semi-aquatic background uses an aqueduct style water
distribution system at the top of the background to feed three separate
waterfalls. The water source is a DIY water bottle power filter hidden in the left
corner behind the center island.
Each waterfall provides continuous water movement throughout for visual
appeal and the health of this semi-aquatic environment.
DIY Aquarium Background Three Waterfalls
Construction of this 20 gallon semi-aquatic
background began with a used aquarium
purchased at a mini-auction during a local fish
clubs monthly meeting.
The peanut shaped in the center will be an
island and is secured to the bottom of the tank
with 100% silicone.
Substrate will go inside and water will circulate
thru and around the walls of the island structure.
The climbing rocks are designed to look like
naturally occurring waterfalls. In this view, the
water channel at the top of the background can
be seen which almost spans the entire length of
the top of the background.
The water channel will be fed by a power-head
pump tucked behind the island and will direct
the water flow to the top of all three waterfalls.
Some styrofoam modifications were made after
the first coat of cement was applied for asthetic
reasons and to help water flow more freely over
and around the artificial rock structures.
Working with styrofoam makes it easy to make
background design modifications even if the
project is well underway.
Several recessed areas were built into the
background to provide hiding places for shy
Another layer of cement has been applied
covering the most recent modifications as well.
A Do-it-yourself Water Bottle / Power Filter will
clean the water and feed the waterfalls. An
opening was cut in the bottom of the bottle
which will be used to insert carbon and filter
media and serve as water intake.
