Can live rock touch the tank floor?

I have been doing so much research about using live rock and now I am confused. Can I place the rock directly on the floor of the tank and then add the crushed corral or does the rock have to be stilted off of the tank floor? If it does have to be stilted I am going to use acrylic rods.

 

it can and should be firmly on the bottom of the tank. many inhabitants will knock over rockwork, so it's got to be stacked on a good foundation.

 

it prolly wouldnt hurt to put some egg crate under yer live rock structure to stop any posible dmg to the bottem of yer tank but i havent don that in my tank my rock is sitting on the sand bed
i think the deeper your rock goes into the sandbed the more stable your base structure will be
putting some egg crate on the bottem of the tank will protect the bottem glass for sure

 

Your LR should go in the tank first so it is resting on something secure. If you place it on the substrate, burrowing fish will cause it to topple. Would suggest you use sand instead of the crushed coral. Crushed coral has large particles which allow detritus to pass through more easily.

 

+2 on that one!

 

Well put.

Getting rid of CC and changing to sand was one of my final steps in the battle against hair algae. I won!!

 

That is funny when I was at the LFS I told them I planned on using sand and they said it was a bad idea. They said when I clean the sand it would be sucked up into the gravel rock cleaner. I am glad you have told me this and I am sticking with my original idea SAND.

On a side note how do you clean the sand without losing any?

 

Live sand here!!!!!!!!

 

I don't know many people who clean their sand. We just buy sand sifting critters to keep it clean for us

 

I thought that was what you would say. Which critters do you recomend?
