Gotcha ... I was like dang that's alot of glue lolNot exactly. Say your attaching two rocks together. Place the 2 rocks together, apply super glue at the connection point, then sprinkle baking soda over the super glue. Once that holds... you can add more glue and baking soda to buff up the connection point to make it more blended. This way... it looks like the rock is solid instead of two rocks glued to each other
I was thinking of back half of the top rock to create a little couple inches height to increase the overall height of the scape and also easier for corals that need to be closer to the light with higher par
