20 tanks per system, 10,000 litre capacity
each tank
Poly tank - strong and durable without impacting water
quality
Green Color - scientifically proven to reduce stress in
stock
Concave bottom to ensure quick removal of waste
|
|
 |
Located in centre of tank, filters water from top of the
tank
Removes uneaten food quickly
In blackout (power failure)- ensures there is always water
in tank, by stopping gravitational draining to screen
filters |
|
By introducing high volumes of air at the bottom of the
pipe, a venturi is created which picks water and solids up
from the bottom of the tank and pumps it into the stand pipe
for instant removal to the screen filters |
|
2 Filters per system
Central collection point for all solid waste, removes waste
up to 50 micron in size
Gravity fed to ensure that solid wastes do not break-up
that causes ammonia problems within the system, which
can kill finned fish in intensive recirculation systems
Reduce the use of water in back flushing operation as screen
filters do not require back flushing |
| |
Reduces load on pump
Point to add medicinal chemicals
Hydrochloric Acid - adjust pH in water and reduce the toxicity
of any ammonia present until bio-filter bacteria are
present in the require numbers
Salt - to cure most skin ailments of fish. Only used when
completely necessary
Bicarbonate Soda - used on a daily basis to keep the pH
steady at reading of 7, which is the optimum for fish growth

Also known as protein skimmer in aquaculture industry
Vital component of recirculation system
Removes protein created by fish slime in the water
If slime is left in the water it becomes an irritant causing
mucus build-up on fish gills
Protein build up on gills reduces the fish's ability to
breathe this makes it susceptible to disease and can eventually
cause death
Ideal component to interact with the ozone generator. Ozone
can be injected into the foam fractionator and oxidises
the dissolved waste products and any disease pathogens present
in the water |
|
Ozone gas is added to
aid the bio-filter during heavy stock load and to promote
oxidation (process to remove ammonia
and nitrogenous waste)
Helps to disinfect bacteria, algae and viruses; removing
colour and odours
Could increase the system capacity by as much as 30 - 50%
Ozone generator requires a reliable supply of clean, dry
air via air dryers or pure oxygen, which can be generated
an oxygen concentrator
The by-product of ozonisation of the water is oxygen, which
ensures the health and quality of fish
Ozone should only be added under controlled conditions,
as too much can be harmful to fish and humans |
|
2 water pumps of 2.5 horse power required
per system
Picks up water from the sump and sprays it into the bio-filter
Ideal pump for the recirculation system and delivers excellent
flow rates and water exchange per tank
Easy to maintain |
|
Supplies atmospheric oxygen to all tanks via 300mm air
stones (3 per tank)
Feeds the airlift ensuring that solid waste is quickly
removed from the tanks |
|
Consists of a combination of bio-balls and drinking straws,
housed in a special tank.
The bio-filter houses two forms of bacteria (Nitro-somas
and Nitro-bacta) that are naturally occurring in all water,
and feed on ammonia and nitrite to prevent poisoning |
|
Each bio-ball is the size of a golf ball, but allows a
meter of surface area for bacteria to grow on, which removes
nitrite and ammonia
A combination of bio-balls and drinking straws create surface
area for beneficial bacteria to grow on
The straws reduce water tracking, ensuring all bio-media
is used to reduce the likelihood of an ammonia build-up
killing fish stocks |
