Hey! Glad to see another 30g out there!!!
Tank looks nice so far but i must tell u that using crushed coral is a bad idea. Thats how my friend started his tank then he switch to live sand. U dont absolutyl have to but if I were in ur position I would go with ls. Also Every one will tell u to cycle with a dead shrimp,thats there opinion,mine is to cycle with a nice damsel(id rather see something swimming than floating) I cycled my tank with 3 damsels, an anenome, lr ,and ls and every thing is a ok(BUt I got lucky with the anenome,I didnt even know there was a cycle when i bought it)
HTH
P.S. dont be afraid to spend money ,if u dont spend alot now ull be spending even more later
