Aquascaping your live rock can be a tricky and daunting task. The rock doesn’t fit together quite right the first few positions you try, and that piece you got just right just fell off and shifted the entire structure. On top of that, your significant other is in the background telling you where to put things or that the way you have it is ugly. To better design your rock structure, try building outside of the aquarium first. Make a boundary with some tape, making sure to account for any overflow boxes, then start positioning the rock. You might also try drilling the rock and fixing the pieces together with acrylic rods, zip ties, or some type of reef safe cement or epoxy.
