Tank building time

[spit.fire]

So I've decided that in the next week or 2 I'm gonna build an 18x20x10 nano tank that will be plumbed into my frag tank to hold all my zoa, sun coral and dendro frags

Still undecided wether to go with a steel stand sheeted in with wood or a all wood stand to match my frag tank

Also lighting is a concern, I want to go led and I was thinking a par 38 but I'm not sure if that will be enough

Any suggestions?
