For
those


instances


such

as

hobbyists,


schools,


and

small


commercial


growers,


corrugate


steel


tanks


and
Polyethylene

tanks


are


a

quick,


economical

way


of


constructing


a

tank


and

getting


the


show


on

the


road.



Both
come

in


a

number


of


sizes


as

mentioned

earlier


for


the


steel


tanks


and

as

for


Polyethylene


tanks,


the


most
common

sizes


are


the


300,


500,


800,


and

1200


gallon

tanks


and

both


may


normally


be

found


at


Tractor
Supply
Corp.
Rectangular

Tanks
In

an

Aquaponics


system

you

can

use

rectangular


tanks


to


utilize
available

space

better

than


round

or


odd

shaped


tanks.



These


types
of

tanks


can

be

built


using


a

number


of


different


ways


and

you

are
only

limited


only


by

your


imagination.



Regardless

of


which

design


you
choose,

it

is


suggested

that


some


measure


be

taken


to


raise

the


sides
steeply
to


a

sufficient


height


above


the


ground

to


keep

out


aquatic
intruders,

mainly


frogs,


but


snakes

are


not


unheard

of


especially


if

the
frogs

are


present.
Inside
a

greenhouse


most


anywhere


or


outside


in


warmer


climates,


an

excavation


can

be

dug

in


the


earth


with
one
end

slightly

deeper

than


the


other


to


aid


in


the


collection

of


waste

and

lined

with


a

heavy

mil


greenhouse
black

vinyl.



The


earth


removed


from

the


desired


area


can

be

banked


up

around

the


top


edge


of


the
excavation.

when


the


vinyl


liner


is


put


into

place,


there


should


be

a

sufficient


amount


of


excess

to


lap


over


the
top

of


said


perimeter


of


dirt.



The


added


dirt


around

the


edge


will


also


help


increase


the


depth


of


the


tank.
When
filling


the


tank,


do

so

slowly


making


sure


to


gently

pull

out


as

many


of


the


wrinkles

from

the


vinyl


as

you
are

able


to


do

to


make


the


bottom

and

sides


as

smooth


as

possible.


You

can

carefully


fold

the


vinyl


at


the


corners


making


a

neat


corner
and
the


water


pressure


will


hold


them

in


place.
After
the


tank


is


filled,


the


top


sides


of


the


vinyl


may


be

pulled

over
the

banked


earth.


You


can

then


place


more


earth


on

the


outer


edge
of

the


vinyl


to


hold


it

down


securely


and

decorate


the


edge


with


stone.
One

other


method


would

be
to

build

up

the


sides


with
landscaping

timbers


which
you
can

purchase

at


most
home

improvement


stores.



A
height

of


about


2

or


3

feet


is
usually
sufficient


to


keep

out
the

frogs,


but


don't


forget,


it
you
tank


is


outside


are


not
secure,

Raccoons


will


be

more


than


happy


to


raid

your


installation


nightly


for


a

tasty

fish

dinner.
After
you

have

reached

your


desired


height,


you

can

then


wrap

the


plastic


over


the


top


and

fold

it

under

3

or


4
times

and

using


small


squares

of


rubber


cut


from

an

bicycle

inner


tube,


place


nails

about


every


3

to


4

inches
