Substrate
So when my new tank arrives I'm debating on whether to go with sand or crushed coral for a substrate. I've read that if you're planning on doing a reef you need a lot of water movement which can disturb the sand and blow it around. I do like the look of the sand but don't want to sacrifice water clarity by having it blown around.
I also know that the live sand acts as a bio filter and I like the idea of that combined with LR.
I'm curious as to what most people who are reefers do? And also if they're happy with the substrate they have or would do it differently.
