Q & A
What is aquaponics?
-Aquaponics is a method of growing plants in water while simultaneously rearing fish. It combines the best aspects of hydroponics and aquaculture, allowing plants and fish to thrive in a mutually beneficial system.
How does aquaponics differ from hydroponics and aquaculture?
-In hydroponics, plants are grown in water, which is often discarded after use. In aquaculture, the water becomes toxic for fish due to waste accumulation and needs to be replaced. Aquaponics solves both problems by recycling water between plants and fish. The plants absorb the toxic nutrients, cleaning the water for the fish.
What role does the nitrogen cycle play in aquaponics?
-The nitrogen cycle is critical in aquaponics. It converts toxic ammonia, produced by fish waste, into less harmful nitrates through beneficial bacteria. The nitrates are then used by plants as nutrients, which cleans the water for fish.
What are nitrifying bacteria, and why are they important in aquaponics?
-Nitrifying bacteria, such as Nitrosonomas and Nitrobacter, convert harmful ammonia into nitrites and then into nitrates. This process is essential for maintaining water quality and providing nutrients for plants in an aquaponic system.
What is a biofilter, and how does it work in an aquaponics system?
-A biofilter provides a surface for beneficial bacteria to live. It consists of inorganic materials like gravel or hydroponic substrates, where bacteria convert ammonia into usable nitrates, cleaning the water before it returns to the fish tanks.
What equipment do you need to start an aquaponics system?
-To start an aquaponics system, you need a fish tank, media beds (for growing plants), water pumps for circulation, and optionally water heaters or coolers depending on the climate. You may also want biofilters and raft beds for growing plants.
Why is it important to test water regularly in an aquaponics system?
-Testing water regularly is crucial because fish are sensitive to changes in nutrient levels and pH. Regular water testing ensures the system remains healthy for both the fish and plants.
What are some tips for beginners starting an aquaponics system?
-1. Start small to gain experience. 2. Choose plants and fish that are suitable for your climate. 3. Test your water frequently to monitor nutrient and pH levels.
What are the benefits of using aquaponics over traditional methods of growing plants or rearing fish?
-Aquaponics is more sustainable, using less water by recycling it between plants and fish. It also reduces the need for chemical fertilizers and allows for faster plant growth due to nutrient-rich water.
What kind of plants and fish are recommended for aquaponics systems?
-The choice of plants and fish should be based on your local climate. It's important to select species that complement each other and thrive in similar conditions. For example, warm-water fish and heat-tolerant plants may be more suitable for tropical areas.

đ± What is Aquaponics?
Aquaponics is described as a system combining aquaculture (raising fish) and hydroponics (growing plants in water). The plants and fish benefit each other, with plants using the fish waste (nutrients) and filtering the water, which is then reused in the fish tank. This saves water and makes the system efficient, blending the strengths of both hydroponics and aquaculture.
đ The Nitrogen Cycle in Aquaponics
The core of aquaponics is the nitrogen cycle, which transforms fish waste (ammonia) into nitrates, a valuable nutrient for plants. This process involves nitrifying bacteriaâNitrosomonas and Nitrobacterâthat convert harmful ammonia into less toxic nitrates, making the water safe for fish while providing plants with nutrients. This symbiotic process is vital for a healthy aquaponic system.
đŹ The Role of Biofilters in Aquaponics
Biofilters are essential in aquaponics as they provide a surface for beneficial bacteria to thrive, aiding in the nitrogen cycle. These filters can be made of materials like gravel or hydroponic substrates. As water passes through the biofilters, ammonia is converted into nitrates, which plants absorb, ensuring the water remains clean and safe for the fish.
đ§ Essential Equipment for Setting Up Aquaponics
The video outlines the basic equipment needed to start aquaponics. These include a fish tank (made from materials like steel or plastic), media beds for plant growth (similar to biofilter materials), water pumps to circulate water, and optional equipment like water heaters or coolers for temperature control. Beginners are encouraged to start small and scale up as they gain experience.
đĄ Top Tips for Starting Aquaponics
The video concludes with tips for aquaponics beginners. Tip 1: Start with a small system to build confidence and experience. Tip 2: Choose fish and plants suited to your climate, as mismatched species can be costly to maintain. Tip 3: Regularly test water for nutrient and pH levels, as fish are sensitive to fluctuations. Affordable testing kits are available online. The video ends by encouraging questions and offering an e-book for further learning.

welcome to agriculture academy
in today's video we are going to take a
look at aquaponics
what is aquaponics how does it work
what do you need to get started all of
these questions are going to be answered
in this video
stick around until the end of the video
for some top tips on getting started in
aquaponics
as well as your own copy of our
aquaponic e-book
before we begin we want to thank you for
supporting our channel and choosing to
watch our content
if you would like more information on
all things agriculture
remember to subscribe to our channel now
let's get started by answering the
question what is aquaponics
in a nutshell the name says it all aqua
means water and phonics means to work or
grow
so basically aquaponics is a method of
growing plants in water and using this
as a habitat for rearing fish too
by growing plants and raising fish
aquaponically you take advantage of the
best of both hydroponics and aquaculture
in hydroponics you are merely growing
your plants in water which most often
gets pumped out the system
in aquaculture toxic nutrient
accumulation from the fish
fish food and fish waste means the water
also needs to be constantly siphoned off
and replaced with a clean supply
however both these problems are solved
in a mutually beneficial way in
aquaponics
not only is water saved through the
continuous cycling from the fish
to the plants and back to the fish again
but the plants are able to use up the
toxic nutrients making the recycled
water safe for the fish again
now that we have defined aquaponics we
need to understand how the process works
there is one process at the core of the
system upon which everything depends
this process is the nitrogen cycle if
you remember
we mentioned that by placing plants into
the system they clean the water and make
it safe for the fish again
the nitrogen cycle makes this all
possible it all starts with ammonia
ammonia is a waste product from the
respiratory cycle of the fish
as well as decomposing fish food and
fish waste
when ammonia accumulates in high
concentrations it becomes toxic to the
fish
on every dark wet surface in the
aquaponic system exists nitrifying
bacteria known as nitro simonas
these are naturally occurring and
extremely beneficial because they
convert the ammonia to nitrite
unfortunately nitrite is even more toxic
to the fish than ammonia
luckily there is another class of
bacteria called nitrobacter which
convert the nitrites to nitrates
and this is fantastic because nitrates
are a great nutrient source for the
plants
so as you can see the nitrogen cycle is
an extremely important process that
converts toxic waste products into less
toxic nutrients that the plants can use
now that the importance of the nitrogen
cycle and the beneficial bacteria have
been made clear
we are going to highlight the role of
something called a biofilter
bio filters can be made of any inorganic
substance like gravel or a hydroponic
substrate for example and are included
in an aquaponics system
to provide a place for the beneficial
bacteria to live and proliferate
the biofilters provide a large dark and
wet surface area on which the nitro
simonas and nitrobacter survive
water from the fish tanks is pumped
through these biofilters the ammonia
gets converted to usable nitrates
the water then goes to the plant tanks
the nitrates are used and the water is
now safe to return to the fish tanks
if you are feeling inspired to start
your own aquaponic endeavor
then you are going to need some
important equipment to get started
we are going to list the most basic
products that you can use to build a
simple system
perfect if you are a beginner first of
all you will need a fish tank
this can be made from a variety of
materials like stainless steel
lined wood or plastic the size of the
container will depend on how many fish
you are wanting to stock
secondly you will need some media beds
which you will use to grow your plants
in
media beds can be made from similar
materials to the biofilter like gravel
or a hydroponic substrate
if you are thinking of growing your
plants on floating trays then you will
also need some raft beds
whilst your media beds can serve the
same purpose as a bio filter
you may wish to include a separate
system into your design if you have the
space and resources to do so
in order to circulate water throughout
the system you will need water pumps
in order for these to work you are going
to need to connect them to an electrical
system this can come from the grid
or be solar depending on your
preferences
if you live in very hot or cold regions
then you may also want to invest in
water heaters or coolers to warm the
water in the winter and cool it in the
summer
and that is aquaponics in a nutshell as
promised we have some top tips for those
of you who are still tuned in
tip number one start small if you have
little to no experience in aquaponics
rather start with a small system and
expand as your experience and confidence
progresses
tip number two choose your plant and
fish wisely
if you are wondering which species is
best for you first take a look at those
that grow best in your climate
trying to recool water fish in tropical
areas can be quite difficult and
increase the costs of cooling the water
it is also important to use
complementary fish and plant species
tip number three test your water
regularly
fish are extremely sensitive to nutrient
and ph fluctuations
it is therefore important to take daily
or at least weekly water readings
you can purchase simple cheap kits
online or from aquaponics stores
and that brings us to the end of this
introductory video to aquaponics
we hope you learned something new if you
have any questions
don't hesitate to ask them in the
comments you can also find your own copy
of our aquaponic e-book in the
description
thank you for watching we look forward
to seeing you next time
