I'd move it up slowly. Do you have any
PVC pipe? Cut differing lengths, by the inch, and move it up slowly (don't ask me how slow
you'll know) to the desired height (where the final destination/rock is). Either that, or place it there, and if possible, use the "window screen"
acclimation method.
I've used rubble to build a "moat" around my clams and hold it in place until it attaches. I've also used a clam shell, or flat
LR piece to get it to hold, and then moved that rock or shell to the desired place.
30 gallon high? standard? Think of it this way...lets say it is "standard" thats like what.... 17 inches tall? My 75G was just 21 inches tall.... 4 inch difference. Right? Now, if it were 400W or even 250W, I'd think differently. However, if properly acclimated (or as our brothers across the pond say "aclimitized") that would work fine.
