Starting-up and
planting aeros
Fill the system with nutrient solution via the Master
Tank, to the top marker on the Level Indicator
(approx. 75L), this will be about half-way up the
Mesh Pots. Switch on the Air-Pump and you should
see the bubbles fizzing vigorously in each Planter.
It is recommended to use clay pebbles as the planting
media for the Mesh Pot – they should be rinsed
thoroughly, to remove all dust particles, before use.
PLANT!T
Clay Pebbles are ideal.

tiP: For young plants, a low/half dose of
Hydroponic nutrient is advised – see your
nutrient instructions for further advice.
Planting
Choose only strong healthy transplants to put in your
aeros system (if selected plant has been propagated
in soil/coco/soil-type media, it is advisable to gently
wash the root-ball to remove as much of the media
as possible). Ideally the plants will have been started
in propagation plugs, and be well-rooted.
Part fill the Mesh Pots with clay pebbles (or suitable
alternative inert media) and place plants so that the
base of the plugs/blocks, or the roots, are just in
contact with the nutrient solution. Then fill around
them with more pebbles – ideally just covering the
surface of the plugs/blocks.
ensure no pebbles fall into the Planter tank, as
they may block the Master Return Assembly.
Running aeros iV master
The Air-Pumps should be run continuously, including
at night. The Water Pump should also be run
continuously, except when doing solution changes.
As the plants establish, the water level should be
allowed to drop to the second marker on the Level
Indicator (approx. 60L) – this should be your ongoing
fill level.
the master Return assembly must not become
blocked. If growing plants with particularly vigorous
root systems, once they are established and the roots
are starting to fill the Planter, re-position the round
Air-stone over the outlet fitting and the shaped
depression, and the rising bubbles will naturally keep
roots away.
Ongoing maintenance
topping-up with nutrient solution should be done
as frequently as possible, ideally maintaining as
close to chosen 'full' volume as possible. The lowest
level line on the level indicator should be treated as
an absolute minimum level. Topping-up should be
done primarily via the Master Tank, either using the
inspection port if you top up with a watering can or
easy-pour jug, or by lifting the lid and pushing over
to one side (take care the Master Delivery Assembly
does not come away from the water pump), if using
a bucket or larger jug.
tiP: When topping-up with nutrient solution, you
may wish to pour some through the pebbles directly
into each Planter to help prevent a build-up of
unsightly mineral salts on the pebbles' surface.
Solution changing will be necessary to prevent
build-up of impurities and to maintain the balance of
nutrients in the solution. This can be done in
two ways:
1. Occasional full solution change – requiring a
complete emptying and refilling of the system.
Recommended at least fortnightly (do not be
concerned about small volumes left in the base of
the Tanks).
2. Frequent partial water changes – requiring removal
of about 5 litres prior to topping-up (every time
you do so).
This should be done from the Master Tank and the
Water Pump (with an extra piece of 13mm/ ½" hose)
can be used. There is no need to turn off the
Air-Pumps during this process.
nutrient Solution monitoring can be done via
the inspection port on the Master Tank, which is
large enough to facilitate most pH or EC meters. The
re-circulating nature of the aeros IV master means
the pH and EC will always be equal throughout the
system. Always carefully replace the inspection port
cover to prevent algae.
Re-using the aeros
All the parts are re-usable though everything should
be cleaned thoroughly and preferably sterilised (with
boiling water or weak hydrogen peroxide solution –
do not use detergents or alternative
bleaching agents).
