You can come over and see mine if you like.

I agree, worked well for me. I suppose if you are stacking "very" high up in your tank drilling and rodding or epoxy is a good idea. :biggrin:

i drilled my rock and used plastic rods ( they were the adjuster for blinds)
and it worked well but very hard to do with live rock took forever cuz it made a mess of the water with base rock it would be much easier because it doesnt need to stay wet

also the first time i used eggcrate................once your powerheads push your sand around a little bit and exposes the eggcrate it looks horrible not a problem with a deep sand bed but I only had 60 lbs in a 4x2 footprint so its pretty thin


when i moved and redid my rockwork no eggcrate and just stacked rocks so they were stable. I threw probably 1/4 of my rocks into my sump to create move open water in DT and I'm much happier.

I have a variety of different sized rocks and many cave and such with no putty or rods and have had no shifting whatsoever. Just make sure it's sturdy and you should be fine. Unless ur trying to get real creative with overhangs and such.

thank you very much for the offer, but i think i got it now. im not planning on anything too elaborate so i'll just go with using gravity and if anything i'll use the drilling and rod idea. thanks everyone for your input, i remember using silicone with river stones so i thought i had to do similar with live rock. SO EXCITED TO FINALLY GET THIS IDEA OFF THE GROUND!!!!!

"So it looks cool".

I used a sheet of acrylic on the bottom of the tank with acrylic tubes attached to it, like small peers. that way all the rock is solidly supported. I never used any putty or rods or ties either.

no putty or rods here either, and i have overhangs and tunnels plus a 6" orange spot goby who rearranges my whole sandbed several times a day, also under the rocks are many caves from the pistol shrimp and gobys lol:P
