The sand in question is best for using with DSBs. Anything with bigger particals like mentioned is not good for DSB. Bigger particals will kill all the essential and benificial creatures in your DSB because the size is to big for most creatures to successfully survive.
Larger particals like CC in the bottom of a tank is a whole different process. There will be very few living creatures in the there and that is why you have to vacum a CC bottom. Because there is nothing living in the CC and therefore nothing to break down the waste.
DSBs are living with all kinds of creatures that break down detris and so. That is why you never vacum, disturb or clean a DSB. The finer sand the better for people wanting a living DSB. And the sand in question is best for this process. However, it is dead sand and you need to add something to it to sort of charge it and make it live sand. Simply adding live rock to it will certainly help. Also, adding a couple of cups from someone elses Live Sand is a good way.
About once per year there is a fellow on RC who starts a thread for people with DSBs. Several dozen people will send him sand from their own tanks. He then mixes it together and lets it cycle for a while so all the living creatures (too small to see of course) will work their way through all the sand. Then he bags it up and sends it back out to all the people who sent theirs in. This is a great way to sort of recharge your system. Again, Dr. Ron had great threads on this before he quite RC.
Also, you can order LS from several places online to add to your new sand bed. At least once per year you need to add something to it to again, recharge your DSB.
Again, this is only my opinion and the opinion of all who believe in the DSB system. I personally would never have anything else. I want my tank to look like the ocean.
Sorry for my ramblings!!
