I have a question about the placement of my base rock.I plan to have a Lawn Mower Blenny and a cuc. Should the rock be placed directly on the bottom of the tank or put a little sand down first? Any advice would be helpful.Thanks!
The egg crate is a great idea. I wish I would of done this. I guess if you have a deep and bed too, that'll help... I drilled and rodded my rocks. They're not moving unless I remove them. Good luck!I agree with the egg crate. I cut mine to fit, then added a thin layer of sand just to fill the squares. Then I put the bottom rocks on to create my base, most of which is now burried. Then the reast of the sand and finally the rest of the rocks. Very stable. I did space my base rocks out to form some substrate caves for those diggers to enjoy.
