Are
the plants in the pool?
No, the aqua-garden is separate
from the swimming pool. The aqua-garden can be situated alongside the pool with
a wall in-between, or can be in a different part of the garden altogether and
linked via pipes. Please refer to the gallery for examples of this.
How
is a natural swimming pool different from a conventional pool?
Conventional pools use poisons in
the form of chemicals, salt (a different form of chlorine), ionisers, oxygen, copper, silver,
electrodes (etc.) to kill algae and bacteria. The problem with chemical/sterile
pools is that nutrients tend to build up over time, creating perfect conditions
for algae and bacteria to bloom. This is why you need to use more and more
chemicals in normal pools – because there are more and more nutrients in the
system. Natural swimming pools need less and less care as nutrients are stripped out of the water leaving nothing behind for
algae or bacteria.
How
much work is involved?
Very, very
little. Aqua-design
natural swimming pools are designed to be self-cleaning as far as possible.
Leaf skimmers need to be emptied regularly, but for holidays away, they can be
removed and the leaves will be digested by the ecosystem. Occasional vacuuming
of the swimming pool is needed.
How
much space do I need?
The size of the aqua-garden
varies according to conditions on the property. A rule of thumb is equal
surface area between swimming area and aqua-garden, but we have succeeded with
a lot less. It depends very much on the environmental conditions that we have
to work with. Generally, the bigger the better.
What
about mosquitoes?
Mosquitoes only grow in low
oxygen environments where they have no predators: e.g. in stagnant pools. The
water in natural swimming pools is highly oxygenated. The ecosystem supports a
diversity of predators such as dragonfly larvae, water beetles, skimmers, that
eat mosquito larvae. Therefore – no mosquitoes.
Are
natural swimming pools more energy efficient?
Yes, significantly smaller pumps
are needed because there is no preassurised sand filter. aQua-design
has also developed an extremely efficient pumping technology which requires an
even smaller pump. Wind/solar generators are an optional extra with some of our
designs. Aqua-design eco Pools use less than 60% of the electricity than any
other system available.
Can I
keep fish in the system?
Yes, a small number of fish can
be kept in natural pools as long as they are kept in the swimming part of the
pool and are not allowed to go into the aqua-garden where they would destroy the
animal life. The fish should not be fed.
And
ducks?
Not such a great idea. Ducks tend
to carry a large quantity of nutrients into the system. Some of our pools play
host to Egyptian geese and migrating wild ducks and we haven’t experienced too
many problems, but if it can be avoided, domestic ducks should be kept out.
Do
natural swimming pools use less water?
The plants in natural swimming
pools transpire water, which adds to the evaporation of water from the pool,
especially in sunny, windy weather. However, there is no need to backwash the filters.
Because of the gentle chemistry of the water, there is no erosion of pipes,
fittings or shells and therefore less likelihood of leaks occurring. Slow leaks
tend to seal themselves over time.
How
does the system handle suntan lotion?
Products which have natural or
organic origins are of course preferable, but the ecosystem can generally
metabolise a usual amount of sunblock.
Can I
use the water from natural swimming pools in the house?
Absolutely! One of the wonderful
benefits of natural swimming pools is the clean, safe water. What could be
better than showering in clean, pure water. In fact,
having a tap installed somewhere in the garden where you can rinse your hair is
a great idea – no need for conditioner after that!.
Can
natural swimming pools be heated?
Natural swimming pools are
generally warmer than conventional pools because the aqua-garden acts as a
solar heater. If higher temperatures are required, it can be done, but this
needs to be allowed for in the design. Heated water carries less oxygen – the
fuel of aquatic ecosystems and so adequate oxygenation is required and the
aqua-garden needs to be larger.
Public / school swimming pools?
Natural swimming pools are very
well suited to public and school environments. Their large size means that
nutrients are diluted. Public natural pools are safe and obviously do not
contain the high levels of chlorine that are normally associated with them.
