yep that is BS, no netting required. If the bed is deep enough then the
infauna will not reach the bottom. A good depth is 4-6", you will want all
fine sand. Having larger grain sand is not a good idea, the larger sand
will move up the bed until it is on the top.
To build a DSB you simply add the sand to the tank after you have saltwater
in it and then add your live rock or whatever to start the cycle. As early
as you can find them, you should star adding various species of macroalgaes
to control nussiance algae and provide nutrient export. After the cycle is
over(usually a month or 2, unless you get cured rock) add detritivore kits
from www.ipsf.com and www.inlandaquatics.com, and also trade some sand with
a local reefer if possible. This will provide the necessary critters(found
somewhat on live rock) that eat detritus( fish crap) and aerate the sand.
After this you should hold off on fish for a month or 2(wish i had done
this) in order to establish your fauna population. It is imperative to feed
during these months, critters need to eat too! After a month or so of
feeding your fishless reef it is safe to add fish. A DSB prohibits some
animals, any type of sandsifting goby, sand star, etc. These creatures are
preying on your infauna population while not effectively "stirring" your
sand. A mandarin dragonette is also a bad choice, unless you have a
refugium that can support its immense appetite for copepods. A new pamphlet
is coming out on DSB, in a month or so. I would encourage you to pick it
up, its called "Deep Sand Bed Secrets"
