Drilli live rock???

[Westfield]

Designing a new coral only tank
My thoughts are to have two "mountain/hill on either end sloping at a 45 from the back corner to the front and a hill in the middle merging with the mountains with the heater and filter on either side of the hill.
Question??
Would I be wise to drill a number of 1/2 holes so I can easily add corals and not have to disrupt my design
Clear as mud

Thanks

Yep, Use a masonry bit and fiberglass driveway markers from Lowes or Homedepot to hold any pieces of the rock together. Pre-drilling frag plug holes is also a good idea.

Masonry bit will go thru the rock fairly easily. Getting the rock wet helps as well. All depends on the type of rock
