Sounds like a lot of work to me..... why drill, glue the LR
. I belong to a reef club and no one has glued there LR
. I have 2 tanks and have not glued either tank.
When you add the base layer wiggle it so it touches the bottom and then build up from there moving and wiggling the lr
as you go up. I have a SFE in my 55 and he has dug all over the tank with no issues with 55lbs of LR
If your going reef you will want to move LR
when corals get attached to trade, sell and make room when they get big. IMO
you will be happy if you just take your time and not glue them.
