How to glue rocks together?

[Timanator]

In a FW tank, if I want a rock wall, what do I use thats safe to the livestock that can glue the rocks together?


Thanks.

If you get good pieces that somewhat ineterlock then you can use that....or use the same stuff you would in a reef tank.

I used silicone  and only had 2 or 3 come loose in 7 years.
But it really dose make the tank heavy,

I've seen some information here on the FishBox about haw to make on with styrofoam and a coating of fiberglass.

You can get some stuff called "Aquascape" which is like a putty that hardens up nicely.  You can just add it to a few spots to hold pieces that didn't interlock.  The only issue is that it turns purple which mimics coraline algae in a saltwater set up.

I had an idea reading this thread that may or may not be on topic here, but what about taking a dry tank, lay it on the back, and find some thin or light pieces of flagstone or slate and using silicone, form them in such a way that they would be stable enough or semi permanent, as to when the tank was set upright, and filled with water, you would have a simulated stone wall on the back???

The weight of the rock will peel itself off the back of the tank CF.....you could make yourself a cement/diy background that way though!


Hanson, that is what I am suggesting as well...Tim being a previous reefer he should know about the putty....they make it in gray as well.

EK, where do you find the gray colored putty?  Kevin at "All About Fish" only has the purple colored Aquascape.

Have you checked out Minh from BayArea? Or CityPets.

I think a better question is "what rocks can be stuck together"?
SiliconII will hold together any rock with good "integrity".
I have some strong sand stone that I stuck together about 40 yr ago. I have tried some "flaky" shales that could not be held together; the failure occurs between the rock layers.
I have some fairly soft sand stone (I think from Glen Canyon), I cut it and stuck a few "shelves in a 55 afew years ago (still holding). I have also done that with a strong shale.

I used silicone with petrified wood on the back of a 40g (short 55) and the color matches natural (sandblast) gravel looks great but I did have a couple of pieces that had to be re-attached.  Big problem when I went to move it, it weighs a ton.
