That may be what the label _says_. This is ridiculous, and
would not even be desirable if true! Do you want to remove CO2?
There is also a contradiction, in that it removes copper, but not
trace elements!
It says nothing at all about what is in it.

Recommended by whom?

Yes, but I suspect that if there is enough calcium to measure, there
will be enough for the plants. I add magnesium, because I'm not sure
if there is much in my water, but I add it at the ppm level, which would
scarcely register on test kits.

Copper is, I understand, an essential trace element for plants.
I don't think iodine is. Molybdenum is another essential element.
