through my searching for live sand at a cheaper price i stopped and realized something i had read on a previous post about the ocean not being full of aragonite or silica. What is ocean sand you ask? Its crushed shells, coral and rocks. So.. this lead to me do some thinking about what i can do to make my own. (ya i know this might end up in DIY but its ok) I have cc and my thoughts are to just crush it into a finer grain size and possibly throw in some dead rock into the mix and basically emulate what nature does. If cc is just as good then why not just crush it more? Thats my logic. Any thoughts would be appreciated
