For those with frag tanks, what would you do differently if you could start all over.... Or what advice would you give to someone like me thats beginning a 20g long frag tank.....?

So far I have the tank and it was drilled for me by ace, the stand, and a temporary led lighting system. It's temporary cause I'm going to wait till everything is setup the check if it's enough light. If it is or isn't will probably be replaced by something better eventually.

I will be breaking down my sons aquapod and will transfer most of the stuff from that tank over.
