Looks good. Needs more rock though in my opinion.
Yeah I know! Going to get some more over the next couple of weeks.
Awesome! Dont stir the sand. How long are you leaving your lights on?
I'd cut that down to 10 max personally.
Well, 300L translates to roughly 50ish gallons...right? Either way you'll need a much larger CUC imo. I like a heavier cuc, but try to fill it with smaller snails/crabs. When you start only seeing a handful of larger ones, it is then time to order more. Atleast how I see it.
Currently in my 55 reef I have 3 emerald crabs, 2 lettuce nudibranch, 15 blue hermits, 10 red hermits, 10 nars snails, 1 blood shrimp, 1 cleaner clam, and i'm not sure how many other snails.

My entire build thread. I actually just updated the FTS today.
It's a organ pipe coral. There a soft coral that grows out of a hard tube base. There good but they can be kind of difficult to care for and there are mixed results with them. Do some research and see if you can possibly keep it alive.
