 Onyx
Sand™ is a specially fracted, stable porous gravel
for the natural planted aquarium. Being carbonate rich,
Onyx Sand™ provides an advantage to any plants
able to utilize bicarbonates. Although ideally suited
to planted aquaria, it may be used in any aquarium environment.
Onyx Sand™ is most effective when used alone as
an integral substrate bed, but it may be mixed with
other gravels. Gravel modifiers such as laterite are
not necessary. Onyx Sand™ is not chemically coated
or treated but does have a slight buffering capacity
that may raise pH by 0.1 - 0.5 pH units (depending on
source water characteristics). Although pre-washed,
it should be rinsed before use to remove residual dust.
Dust can also be minimized by filling tank slowly and
dispersing water so that the Onyx Sand™ bed is
not disturbed. Slight initial cloudiness is normal and
will clear rapidly (2–12 hours). This bag is sufficient
for about a 5 cm (2 inch) deep bed in a typical 40 L
(10 gallon) tank. Recommended use is 1 kg (2 lbs)
for approximately each 200 cm2 (31 in2)
of tank bottom at a depth of 5 cm (2 in).
