Spirulina : from salted water or fresh water ?

[Veronica01]

if it is from salt water i wonder how they'd control it and harvest it. I thought chlorella was done in fresh water in japan, but no idea about spirulina.

Minerals from Deep Seawater
Only Hawaiian Spirulina draws nourishment from the world's cleanest, deepest ocean. Our facility uses ocean water drawn from a pipeline that plunges 2000 feet into the Pacific Ocean. Oceanographers tell us this water has been below the surface since Old Testament times. Our pipeline brings this ultra-pure, mineral rich water to our ponds. We supplement our Spirulina systems with this deep seawater as a source of calcium, magnesium, and all 94 trace elements. No other Spirulina is grown with such special water with its rich source of naturally occurring nutrients. In fact, every other producer of Spirulina in the world uses either river water or irrigation water, which is another reason why Hawaiian Spirulina is the purest and highest quality in the world.

so it depends on the manufacturers ???
Spirulina is both salted water and fresh water ?
