Hi, everyone, do you know that tourmaline sand is good for fishes?

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.
After having put tourmaline sand, water of the aquarium for fishes is
activated within 2-3hours. The water molecule group becomes smaller and
amount of negative hydroxide ions is increased. Water quality is clear
and doesn??t generate lichens (the top of the aquaria suffering
from sunshine will once in a while generate some lichens, but they will
quickly become yellow, black and die). It is very fit for survival and
health of fishes.
Put tourmaline granules into domestic aquarium for fishes, the water
can be obviously improved, very fit for survival and health of fishes.
[ Instruction For Use ] '
1. Put tourmaline sand (granule size is about 5mm) into domestic
aquarium for fishes, according to the size of the aquarium and the
sinking height of tourmaline sand is about 2-10cm (usually the height
is 2-3cm).
2. Due to some membranes will be caused by dung of fishes on tourmaline
sand, it is better to clean one time per 2months and to change water
one time per 2-3months.
