do-it-yourself aquarium and semi-aquatic background designs beyond the traditional
My 125 Gallon DIY Aquarium Background

I still have to do a few touch-ups and do some filling
in of the gaps next to the glass and a couple other
I used 1 1/2 and 2 inch thick sheets of
styrofoam. I used approx. 2/3 of a bag of
quikrete in 3 coats. I had to do it all in
sections of 4 layers as the braces restricted
area to maneuver the pieces.
There are 11 caves and I have 2x fx5 filter intakes
and outputs hidden behind the wall. This is my first
project and took roughly 4 hours per coat of quikrete
and probably 5 hours of cutting styrofoam.
I didn't use extruded styrofoam as Lowe's didn't have
it in stock. My next background will be made out of
extruded because it is much more dense and makes
a much smaller mess when shaping.
I know I'm over filtering it but as long as the output
isn't too strong this is the way I plan to keep it. I'll get
more pics up once I get the substrate added and get
my plants to start filling in. I'm using the filters as my
CO2 reactors since they pump from the bottom.
