WOWZER! Now that is a pool! I wonder how the heck they keep that sucker so sparkling!?
From the article:
Chile's monster pool uses a computer- controlled suction and filtration system to keep fresh seawater in permanent circulation, drawing it in from the ocean at one end and pumping it out at the other.
The sun warms the water to 26c, nine degrees warmer than the adjoining sea.
Chilean biochemist Fernando Fischmann, whose Crystal Lagoons Corporation designed the pool, said advanced engineering meant his company could build "an impressive artificial paradise" even in inhospitable areas.
"As long as we have access to unlimited seawater, we can make it work, and it causes no damage to the ocean."
So, filter the sea water at one end and pump it back out the other.
I went down to the Hilton Cancun a few years back when we installed our Pool Pilot systems on their pools and spas, guess where they got the salt water from? City water and Sea Water filtered through a sand filter. The water was crystal clear starting up...
