be careful on "glueing" the rocks in place it makes for harder future aqua scaping. what some ppl do is drill holes in the rocks and ad plastic pegs to hold them in place then you can take them apart and move if need be in the future. i tried using frag putty to hold a few rocks in place as well and it doesnt seem to stick and just pops apart. most of my rocks are just carefully placed as to not cause a rock slide.
but since you are doing the waiting game set up a mock tank out of carboard or wood and pre plan your aquascape gives you time to get that litle bit of perfection without getting as wet
