Hey Denny,
:welcome:
Even if you knew of a very remote beach somewhere in the south pacific that no one ever visited I would be very suspect of putting it in my tank.
But Jersey sand? - Woo.. - NO WAY!
That CaribSea stuff is ok.. - Lots of people have lots of opinions on the commercially bagged stuff, but yeah, what you have is fine.
The deal with ive sand is that you only need a real little bit of it..
What you do is, put the dead (dry) stuff in to get the level of sand you want (people have different opinions there too.) Then after you have that in and your water, go to the LFS and get like a pound of live sand for every 50 gallons of tank that you have. Then, when you get home with it (right away, treat it like it was a sensitive fish) you take and spread it out over the top of your existing "dead" (no longer dry) sand..
All "live" sand is is sand with a bunch of tiny life in and around it. - Not just bacteria, but a lot of times theres tiny stars, pods, worms and stuff that help take care of the "leftovers" basically..
