What Causes Your Pool Water to Turn Green
2
Swimming pools are intended for delight and fun,
which can only be achieved when the pool water is
clean and clear.
3
However, it's similarly critical to keep it free
from different germs and pollutants, and the most
frequent problem that arises is the pool water
turns green.
4
Even after getting your pool up and running,
pulling out all of the leaves and dirt, it may
look clear but by taking a close look, you will
notice that the pool is green or cloudy.
5
Here are the main causes that are responsible for
your pool water to turn green.
6
Causes of Green Water in Pools
7
When you will analyze the condition of the water
in the pool, you will come to the point that
there are mainly three causes of green pool
water--
LACK OF CHLORINE
POLLEN
METALS
8
Lack of chlorine
9
When you find that your pool water has turned
green, then first check the level of chlorine as
it might be the reason behind the rapid growth of
algae.
10
If there is less or no chlorine in the water, and
in the presence of an algae bloom, the pool
becomes unsafe to swim as well as acts as a
breeding ground for germs and insects.
11
When there is a growth of algae, it will start
growing on the pool walls and bottom first.
12
The green water caused by algae can be treated
either by super-chlorination or algaecide.
13
Pollen
14
Another common thing that causes pool water to
look green is pollen that gets carried into the
pool water by the wind and is not removed by the
sand filter as it is very small.
15
And when the pollen builds up in the water and
settles on the liner, the water looks either
green or yellow.
16
However, unlike algae, pollen does not stick to
the pool surface and one can easily differentiate
because the pollen when disturbed, floats up like
a cloud and the algae come up only when it is
brushed.
17
The best way is adding a flocculant and till now
it is the most effective treatment for removing
pollen.
18
Metals
19
A leading cause of green water in pools is
metals, especially copper, that have oxidized.
20
Generally, metals are introduced in the pool
through source water, from some cheap algaecides,
or from the metal components of the pool.
21
When the pool is shocked, then the metals present
in the water gets oxidized and turn the water
green.
22
Despite the color, the pool looks fairly clear
and you can only detect the problem when a clear
pool is shocked and still the water turns green.
23
The best way to treat a metal issue is to add a
sequestrant to the water and the sequestrants
will group the metal particles together and can
be easily filtered out through the pool's filter.
24
In the end
25
A swimming pool needs to be regularly cleaned and
maintained properly to control the growth of
algae and be free of other pollutants like
pollen and metals.
26
Otherwise, your pool water will become unhygienic
for use and even the pool surface will get
damaged and require frequent maintenance.
