Default Activatiing water for fishes

Hi, Dr Engelbert Buxbaum,
Could you explain why you think it is kind of fraud?


Tourmaline can release 0.06mA bioelectricity in the water and
electrolyze bigger molecule group of water into smaller or single one
so as to activate water. Eradiate more than 90% FIR (far infrared ray),
generate above 235p/s.cm3 negative ions to make water presented
alkalescence (PH is 7 ~ 7.5), antibacterial and deodorizing, and
release mineral microelements.


That's not only "kind of fraud", that a total misrepresentation of the
properties of the material advertised.

Turmaline is, if I am allowed to oversimplify a little, a form of quarz
(silicon dioxide), albeit with some other elements added: Li, Na, K, Mg,
Ca, Mn, Fe, Al, Ti, Cr, F, B. Depending on exact composition it can have
all kinds of colours: blue, green, red, brown or black. In the aquarium
it is inert, you can use it just like sand (if you don't care about the
higher price).

Since it is a mineral, not a living organism, it can not "release
bioelectricity". Bioelectricity happens in our nervous system on the mV
scale, some organisms (electric eel, electric ray) are able to create
several 100 Volt for self defence or hunting.

Turmalin shows piezoelectricity and thermoelectricity, that is a voltage
appears between the ends of its crystals if they are compressed or
heated. Nota bene: A voltage, not a current as stated in this add. A
permanent current can not be created this way.

Water molecules indeed assemble into clusters, the size of these
clusters is strictly temperature dependent and can not be changed by
electrophoresis (even if that were to occur, which it isn't).

Far infrared ray is at best bad therminology. Far infrared radiation is
simply heat. How is turmalin supposed to change that?

Because of the fundamental principle of conservation of charge (which is
just as invariant as mass and energy) you can not just "create negative
ions", but only pairs of negative and positive ions.

A unit p/s.cm3 would be a force (in Pond, the old unit of force used
before we changed to SI) divided by time (second) and space (cubic cm),
this has nothing to do with electricity. Possibly pS/cm3 is meant, which
could be a scrambled version of the conductivity (S/cm). But tank water
has conductivities between uS/cm (soft fresh water) and mS/cm (sea
water), adding a few pS/cm would increase the conductivity by 1 in a
Million to 1 in a billion: irrelevant. And note that it is cm, not cm3.

"Alkalescence" does not exist, possibly alkalinity is meant. But pH 7 to
7.5 is more or less neutral, and turmaline does not change the pH - as
mentioned it is inert under tank conditions.

For this reason turmaline also is neither anti-bacterial not
de-odorising. And the amount of trace elements released into the water
is so small that it's insignificant.

In short: you have been had.
