If you're planning to have wavemaker, finer grade sand may get blown about. Especially for SPS setup where folks typically want stronger flow. On the other hand, if you're planning for LS such as star fish, mandarins, gobies, or other inverts & corals that lives on the sand bed in their natural environment, then choose sand instead of coral chips.

Otherwise, going for BB will be lowest in terms of maintenance effort.

You might have to go with grade 1 sand and above. Grade 2 sand is slightly larger than grade 1 and so on and so forth.

For me I go for SSB 1.5inch grade 1 sand for my main tank for nature look.Inside refugium on sump tank will be 2inchs grade 1 sand to grow pods and cheato.
