Build a breathable sea in the heart of the city:The long-lasting blue vitality behind Tianjing Lake — Large Water Body Purification System

Many property owners of the Hudiewan project in Qingyuan, Guangdong often ask: Why does that vivid, crystal-clear "Tianjing Blue" remain flawless all year round?
 
Why does this vast stretch of "water sea" never turn green and murky in just three years like ordinary landscape lakes?
 
The answer lies in one key reason: we have endowed Cyanthos-lake with a breathing heart.

Bid farewell to stagnant still water: Let the entire lake come alive on its own.

Traditional lake water purification is like giving a patient an intravenous drip — it only addresses the symptoms, not the root cause. Once the water pump breaks down, the water turns foul.
 
As "a sea in the city", Cyanthos-lake boasts a water volume of tens of thousands of cubic meters. Faced with such a vast expanse of water, it is impossible to filter it like water in a fish tank.
 
Therefore, we adopted a brand-new approach: instead of creating artificially purified water, we restore naturally circulating living water.
 
We apply a complete large-water-body water purification solution. This system acts as a huge ecological kidney for Cyanthos-lake. Operating silently and steadily, it creates the intoxicating texture of a crystal-clear jelly sea.

No mere landscape, only pure ecology.

Many lakes in cultural and tourism projects are merely for viewing, fenced off with signs reading “No Entry into the Water”.
 
The waters of Cyanthos-lake, however, are meant for people to immerse themselves in.
 
Our water purification philosophy is not to turn lake water into sterile, tasteless distilled water — an environment unsuitable for water recreation — but to achieve high-standard water-contact safety.
 
Through overall coordinated operation of integrated equipment, we have built an invisible purification matrix at the lake bottom. Extremely efficient, it easily handles the pressure brought by thousands of tourists during peak seasons. Exceptionally stable, it can restore the iconic Tianjing Blue in a very short time, even after turbid downpours.
 
Here, the water is alive.
 
When the wind rises, it surges like ocean waves; when the wind calms, it glistens as translucent as coloured glaze. This dynamic beauty is sustained by a quiet, reliable and always operational water purification system working silently behind the scenes.

Why is it known as "the sea in the city"?

For we have recreated not only the sea’s breathtaking hue, but also its natural self-purification capacity. The greatness of the ocean lies in its powerful self-regulation. The integrated water purification system of Cyanthos-lake endows this artificial lake with the same self-healing power as the sea.
 
For operators, it means ultra-low maintenance costs and superior water purification performance. For every visitor, it guarantees that Cyanthos-lake remains as crystal-clear and captivating as your first visit, all year round. The water purification system works just like air — utterly unnoticeable, yet utterly indispensable.
 
When you run along the lakeside sandy shore of Cyanthos-lake, 
when you watch your children play and splash safely in the shallow water, 
when you capture stunning blue scenery photos with no filter needed…
 
Always remember, deep beneath this sea within the city, 
a powerful heart beats quietly and steadily.
 
Cyanthos-lake — your premier destination for urban micro-vacation.
