“Live
Sand” , at first glance might appear to be plain old
sand (wrong!). What makes this sand “live” are
the millions of beneficial bacteria, worms (yes, worms!)
and other microcrustraceans and
other lifeforms
that typically inhabit this unique “sand”.
These beneficial (actually crucial) lifeforms are, to a great
degree, a large part of the filtration system itself that
not only helps keep your system healthy, but removes (metabolizes)
much
of what
would
be waste material you would (in the “old days”)
have to remove manually through the use of a gravel vacuum
or some
other device. Much has changed.
Live sand is largely made up of crushed coral resulting
from storm damage and natural decay processes. What most
people regard as “sand” is Silicon Dioxide
and is actually detrimental in a marine aquarium. Live sand
is also beneficial because of it's composition, mainly Calcium,
and is crucial to the marine aquarium environment. The salinity
(and high pH) of saltwater causes the Calcium in the sand to
slowly dissolve into the water which is then re-absorbed
by nearby living
reef animals
and helps to rebuild new coral reefs. Once again, as we use
the nature as our guide, and we try to replicate that
environment, it takes care of itself and there is no maintenance
involved to keep it healthy.
Over time, because some of the minerals in the live sand
will dissolve, you will need to add a few handfuls of new
sand (once every six months to a year). This is
also a good
thing
because
when you add new sand, you also introduce new species of beneficial
bacteria which adds to the overall biodiversity (a very good
thing!)
and keeps
the system healthy. |
