I bought carribian live sand to kick start my tank and of course live rock the sand is packaged wet and as long as it dosent get frozen should be pretty beneficial bought mine at big als forget what i paid though

sugar or less fine?

I am not a fan of the fine sugar sand, it blows around too much. I use the courser stuff.

I use the Sea chem select I love it its just right and not too light hardy any fine dust either...
