Rock Structure

[Hdhuntr01]

I am putting together a 150G and am using dry rock and dry sand. I have the center rock structure built weighing about 60Lbs and epoxied together firmly. It seems to be very stable and doesn't rock back and forth but I hate putting this structure against the bottom glass. Has anyone used something to pad between their rock and the bottom glass? If so please explain to me what and how...

Thanks,

you can use plastic eggrate material but I'm not sure how it would fare with 60lbs of rock sitting on it. In that case, making a stabilizing structure out of pieces of PVC cut in half might prevent too much rocking of the structure

You could buy starboard AKA a white plastic cutting board they are the same thing, and you could cut it into small sections with a hacksaw, set it on those and epoxy them in place.

Or just not worry about it because it will be significantly lighter in water than it is in air.
