caution

to


prevent


problems

later,


always

remember,


after


the


holes


are


drilled,


you

must


make


sure


there


are
no
obstructions


in


the


holes


and

also


clean


out


the


inside

of


the


tube


carefully


removing

all


filings.



A

possible
solution

is


the


use

of


a

heavy

grit


piece


of


sandpaper


wrapped


and

tacked


around

a

wooden


dowel


and
rammed
through


the


PVC.



Then


use

a

high


pressure


air

nozzle


to


insure


no

bits

or


pieces


of


the


drilling
process

were

left


to


later


block


the


air

holes.
Backyard

&

Hobby


Systems
Aquaponics

is


a

great


hobby


and

an

even

better

way


to


produce

food


in


your


own


backyard.


A

small


backyard
aquaponic
system

can

produce

enough


food


to


feed


your


family.
System
Design
Backyard
aquaponic

systems

use

the


following


equipment.
One

pump


only


-


for


energy

efficiency
medium
bed

hydroponic


components
Tubing
for


water


delivery


to


and

from

the


grow

beds
Thermostatically

controlled


aquatic


heater


to


maintain


the


required

water


temperature


in


the


system
water
The

use

of


clay


or


gravel


hydroponic


grow

bed

medium
The

necessary

kits

to


test


the


pH


of


the


water


on

a

regular

basis
The

Pump
A
properly

designed

and

constructed

system

will


only


require

one

pump


to


operate


efficiently.



When

you
locate
the


outlet


from

your


grow

bed

higher


than


your


fish

tank,


only


one

pump


is


required

to


move


the


water
from
the


fish

tank


to


the


grow

bed

and

then


it

is


returned


to


the


fish

tank


through


tubing


by

gravity


flow.
Grow

Bed


Hydroponic


Component
Gravel

used

as

a

grow

bed

medium

is


the


most


efficient


hydroponic


component


for


a

backyard

or


hobby
system.
This

is


due

to


several


reasons:
good

plant


support
higher

plant


growth


&

yield
better
water


buffering
Additionally
the


gravel


will


act


as

both


a

bio


and

solids

filter.
For
systems

not


using


gravel


in


the


grow

beds,


more


water


filtering


components


are


required

which

raises

the
cost

of


system

construction.
Constant

Flow


Water


Delivery
Ebb

&

Flow

system

of


water


delivery


to


the


gravel


beds

is


done


because


it

enhances


root


zone

oxygen


and
