New Dry Rock

[Ryeguy1284]

So I ordered 80 lbs of dry rock. Well it showed up today I open the 2 boxes to find 1-38 lb rock and 2lbs of rubble in one box and 2-15 lb rocks w/ a 3 and 8 lbs rocks is this normal? In the past I’ve always gotten a mix of sizes. Any suggestions on cutting this behemoth and keeping it looking natural? Here’s a pic of the rock and one of the lay outs with the rocks as is.

A hammer. Thats what I do.
Or drop it in the street and see what it becomes, natural shaping.

I used a hammer and chisel before and it worked surprisingly well. Just go slow and carefully.

Pick up some marco cement, you'll do amazing things with chunks of rock

I haven't used aquastick, so I can't comment on what is or isn't.

So the plywood is the same size as the tank. The other day I seen a nice shelf rock I’m thinking about putting on the left hand side and I’ll have it flush on the left and hang over the right side and front a few inches
