“Ecological pools" which are not biological at all.
the search for customers, some companies switch to "greenwashing" and
sell their products as something they are not. In extreme cases, this
can lead to the situation where a customer understands to buy something
natural and biological, but instead receives a poisonous dummy package.
Hybrid pools use
a different form of disinfection where resistant water organisms may
survive. That allows the use of border plants to give a natural look.
But the biology is not the base of the water purification, as most of
the life forms are killed by the disinfectant agents. It is just deco.
The usual disinfection techniques are UV lamps, copper and silver ions
and electrolysis. That is all fine as long as they are sold as what they
are: chemically poisoned.
is completely wrong is: to sell a Hybrid pool as a Natural swimming
Pond/Pool! That is green washing and unfair competition. Unfortunately
that happens as well on Ibiza.
