I'd do it that way but I'm planning to use some of my fully cured live rock and I don't want it to dry out but I might just buy all new rock if thats easier.Hi mauler,
I'm gonna tell u the same way I was taught a cpl yrs ago or so.
Yes some of us are lucky enough to have a lfs or cpl lfs that order 1000#s of dry rock and u can shift through it... Shelf rock is good too.
Take the measurements of ur tank. Go out to ur garage or even a sidewalk and tape down the measurements. Than play with wat rock u have. Take ur time, u can also use a roto drill hammer bit... Or reg big drill bit. Drill holes and large zip tie em together.
Go minimal with a cpl larger rocks rather than a pile of smalle ones.

Sometimes you have to turn the rock and twist it a little...wiggle and turn it again to maybe another spot until they lock, it takes time, you can't rush, and you can't insist the pretty blue be where you want it. It took me an hour one time to hang on the side of the tank messing with the rock before I got it to finally get into place, but once I got it, man it was not going to move... Point is...keep at it and don't give up, it will lock.I've tried locking them but they don't stay locked so I might just buy dry base rock and make one formation every few weeks
