Jim/Dianne/Aaron:
Thanks for all your helpful answers, I have however made yet another decision about the sand, tell me what you guys think:
I dont want to keep the sand I have now as it was a bad move to begin with due to impurities, runoff, or whatever else maybe in there, I was impatient, this tank was actually for a surprise for my 3yr old and I wanted water, sand, and a damsel in there when he saw it....but I dont like how this sand looks at all.
So, instead of using the sand from this guy who is tearing his tank down, I am getting reef sand straight from a diver, from the gulf, not sure where from, but not from our neck of the woods up here in Hernando, this guy says it is from minimum 50ft depth, from a reef, says it has all kinds of "life" in it, snails, small life, possible tiny stars, corraline bits something or another, but he emphasized it is full of life.....I did read here on RC that reef sand is good....I should mention, I put a dose of Biozyme a week ago, and another dose today, just so you know more about my water when replying.
So, I'd like to hear back from you guys if this sand will be good.
What I plan on doing is emptying out my tank, totally removing the old sand....also, my water I currently have has been cycling since the 7th of this month, almost 2 weeks ago, should I keep that water, or should I dump it, and use fresh RO/DI water and start from the top?
I appreciate all the comments above....oh Dianne, the sand was from a homeowners property out in Hernando Beach
On a side note, everyone else I have talked to locally and fish stores as well, all told me I could dump damsels in right away after salt, that they are hardy enough, so far no casualties, and my clown is doing great, going on a week and is very active in the tank.
Oh, regarding the history of my rock, the person I bought this setup from they had emptied out the tank a couple days prior to me buying it, and the rocks had were dry....I bought locally the brown rocks you see in the tank to seed the old rock.....however just today I found a big patch of hot pink coraline on one rock that wasn't there, and some small sections of the rock have pink on it, I know it's new because I looked at every square inch of this rock when I got it and saw the old dead coraline as dark purple and I can still see it, and it's different that the new stuff I am seeing.....so something must be going on right in my tank (for an impatient noobee

), there is also alot of dark rust coloring going on on my rocks similar in color to those small brown rocks I have in there.
I hope to hear back from you guys regarding the reef sand and if you think that is good sand for it's properties, and also let me know about dumping the current water when I get this reef sand.
I appreciate all your advice/help.
