JBJ 6 gallon nano reef

[JacksonJigsaw]

Hey guys, looking to start a new tank. Tanks on the way just doing my hw before i start buying things.

The plan is to use
6-7 pounds of live sand,
6-7 pounds of live rock
Stock lighting
stock filter
Chemi-pure in the back
Ill get my water from the LFS, its straight from the ocean (live in south florida)

I wanna just grow small low-medium light corals and have a clean up crew. maybe one VERY small fish.

Any ideas? Hints?
corals that are easy and a fish species that is small enough?

Thank you
