Its a MUDDY mess at first ,,,Their texture isn't suitable for sand bed
creatures, they seem to release silicates into the water, and also contain
various other minerals that aren't good for your tank ...its your tank
,,,what ever works for you man

I have 75lbs of the Home Depot "Tropical Play Sand" in my reef tank. It is
full of critters, it stays milk white, the fish, snails etc all play in it
and it has the gas bubbles evident of denitrification. I did not even seed
it with live sand from LFS! So what's wrong with it in your opinion?

I tried the home depot brands,NOT GOOD!! If your going to do a DSB you
should do it right from the beginning or you will get hell,,,Its what
helps support the system and unless you have 20 cent minnows in the tank I
would not mess with the proven way.Trust me I tried

news Hi the

Do any of you think it would be possible to use tiny glass beads 1-2mm
in the substrate? They would be inert, wouldn't they?

Thanks,
quietreef

I'm sure you could use this as a substrate, but I think it would only be
for
your viewing pleasure. You might do some research on grain sizes of
Deep
Sand Beds (DSB) to find out if this would work at denitrification. Also
you
wouldn't get any buffering capabilities for your system. I'm also not
sure
if detrivores would burrow into glass beads, so it might be a problem
keeping it clean.

Those are just my thoughts. I don't have any real research to back it
up.
I did use glass marbles for freshwater fish breeding at one time, and
glass
is inert, and won't harm the fish. It is my opinion that you should use
an
aragonite sand, and if you don't want to pay a fortune for it, try
looking
for southdown/yardright/old castle brand sand at home depot, or your
local
landscaping companies. Yard right sand is sold as Tropical Play Sand at
some of these places. If you can't find that, I would at least go with
a
decent silica based sand. I do have to say though, that there is debate
on
whether silica based sand is good for your tanks, but so far all the
research I have done, has led me to believe that this is all bunk, and
it is
ok for your tank. But only you can make that decision. -Chris
