Ok, I bought my tank used and the guy before me had crushed coral and I didn't like the looks of it so I kept about 1/2" of the CC and put about 2" of Aragonite (sp?) sand over the top of the 1/2" layer of CC. Now the CC is slowly making its way to the top of the sand making it look like ****. I have been sifting out the peices of CC with a strainer but it is only getting worse.

The reason for this post is that I am wanting to remove all the mixed CC and sand, and put in a whole new layer of just sand. I know that the already CC and sand has the proper bacteria for my tank, and I am wondering if it is bad if I remove all of the CC and sand and put new sand in?

Would this cause my tank to re-cycle? Or what would the proper way to attempt this?

My tank has been up for 1 month. My levels are, PH-8.2, Ammonia 0, Nitrites 0, and Nitrates 10. I have 2 percula clowns, 10 hermits, 1 emerald crab, 1 pepermint shrimp, 1 snail.

Thanks
