12 Gallon nano NEW!

[Breeing]

Hey everyone, new to the saltwater scene!

I am looking into starting out a smaller reef tank, i know it can be a lot more challenging to start out with a smaller reef, but i'm really interested in giving it a go!

Now i am on a budget, and found the 12 gallon JBJ nano cube, it looks fantastic, but reviews are scattered, i am wondering what you all think, and weither or not you have experience with it- if you don't like, what do you recommend?

I am planning on using a Hydor Koralia 240 (or 425?), stock filter, stock light and 50 watt heater for equipment.

RO water, instant ocean salt, 10lbs. Arag-Alive pink sand, approx 20lbs live rock.

Will this work for:
Basic corals, anemone, 1 false perc clownfish (or pair) clean up crew and if not a pair of clowns then a couple smaller fish such a goby, etc.
