That’s really personal preference. A lot of people are moving to the “minimal” look, but i like a complete wall of rock. Just make sure you don’t have so much Rock that you’ll have dead spots. If you have Little Rock in your display but want more bio filtration, add some in your sump to make up for it
I will be running a Tidal 75 with sea chem matrix in a filter bag And some filter floss that’s it, gonna keep the bioload very minimal 1 clown fish and snails and see how things go. Will mostly be doing softies, zoas etc
