Pre-drill your live rock with a quarter inch masonry drill bit. Drill all new corals up through the bottom and affix a short length of acrylic rod or rigid airline. This allows you to place the coral in a stable manner, but also to move it around as the need arises.
For coral pieces 1/4 inch max, 2 inch deep. Buy the rods first and match the rods accordingly. Don’t use a hammer drill as it will shatter the rock. Drill into a solid part so it has a firm base that won’t fall apart.
Bigger 1 inch+ holes are good for running PVC pipe with fittings (45s, 90s, tees) for holding heavy reef structures. You can use a diamond hole saw designed for glass drilling to make these big holes. They are remarkably easy to drill.
