of


their


process.


This


condition


will


drive

the


pH


of


the


water


down


and

it

therefore


becomes
important

to


also


monitor


the


pH


numerous


times


per


day

and

adjust


it

according


to


the


desired


pH


for


your
system.
WASTE

REMOVAL
Solid

waste

comes


in


the


form

of


fish

excrement,


uneaten

food,


trash/dust


particles


blown

in,

and

other
unknowns

which

come


from

"somewhere".



Physical


removal

of


said


waste

should


be

done


on

a

schedule


so
as
to


not


allow


it

to


build

up

too


much


as

it

can

be

responsible

for


70%


of


the


nitrogen

load


in


a

system.
Solid

waste

causes

heterotrophic


bacterial


growth


which

in


turn


produces

additional


ammonia

in


the


system.


A
sump


tank


configuration


is


a

great


way


to


make


collection

of


said


waste

much


easier.


SUMP

WASTE


COLLECTOR
Illustrated

below

is


a

sump


or


settlement


tank


which

can

also


be

incorporated

into

this

system.



It

contains


a
baffle

which

effectively


allows


the


heaver

fish

waste

to


settle


to


the


bottom

of


the


tank.


The


waste

can

be
allowed

to


collect


there


and

removed


after


a

period


of


time


to


be

used

in


organic


potting


soil,


feed


your


worm
bed
etc.
This

is


a

good


way


to


prevent


the


waste

from

being
pumped
into

the


grow

beds

where


over


a

period


of


time


it
could

possibly

collect


in


the


medium

near


the


water


outlet
holes

in


the


PVC.



This


could


restrict

or


create


a

diverted
flow

of


water


into

channels,


preventing

the


plants

the


full
benefit

of


the


water


or


in


some


cases,


receiving


none


at
all.
TANK

DRAIN

SYSTEM
A
drain


system

should


be

placed


in


the


bottom

of


the


tank


to


pull

the


water


primarily


from

the


lowest


point


of
the

tank


or


where


tank


design


designates


waste

collection

to


be

concentrated


most.


The


water


then


moves


to
the

Sump

Tank


for


waste

collection.



The


drain


may


be

installed

using


PVC

connections


through


extra


added
layers
of


rubber


or


vinyl


and

sealed


with


a

generous

application


of


silicone


sealant.
Aeroponics
Aeroponics

is


the


process


of


growing


plants

in


an

air

or


mist


environment


without


the


use

of


soil


or
an
aggregate


medium

(known


as

geoponics).



Unlike


Hydroponics

which

uses

water


as

growing


medium

and
essential

minerals


to


sustain

plant


growth,


Aeroponics


is


conducted

without


a

growing


medium.
Because

water


is


used

in


Aeroponics


to


transmit

nutrients,


it

is


sometimes


considered


a

type


of


hydroponics.
Ideally,

the


environment


is


kept


free


from

so

that


the


plants

may


grow

healthier


and

more


quickly

than


plants
grown

in


a

medium.



However,


since


most


Aeroponic


environments


are


not


perfectly


closed


off


to


the


outside,
pests

and

disease


may


still


cause

a

threat.
Controlled
environments


advance


plant


development,


health,


growth,


flowering


and

fruiting


for


any

given


plant
