To Reef Central The calcium cabonate won't cause any harm, but coarser substrates tend to accumulate detritus and become a maintenance nuisance, IME. I stick with a fine grain of sand now.

The finer grained sand (oolitic) gets my vote hands down

I can agree that it's generally best not to use a coarse substrate.
I vacuumed my substrate, but when I took it out to switch to sand, there was still a lot of nasty stuff beneath it. |

I started with crushed coral and switched to sand. I sand is much easier maintenance and has led to a lower nitrate level.
