100-150 pounds of base rock with 50-100 pounds of live rock on top
Sounds good. If you can hand pick, go for it. Also, you don't necessarily have to use the base on the bottom IMO
. You can mix it here and there according to fit while you're constructing I believe.
Be careful with adding uncured liverock after you cycle. May go thru another if a decent quantity of rock is added. I'd put it all in together and cycle once.
I'd consider driving the 1.5 hrs if you could in order to handpick the stuff -dry and live that you want. It'll be worth it IMO
