Oh CRAP!!!! and I thought my rock wall looked great

Is it made of that foam stuff? I have read people silicone it to the back glass. Weight has nothing to do with buoyancy by the way. /DesktopModules/ActiveForums/themes/hybrid//emoticons/smile.gif

 

can you attAch some base rocks to the bottom of it

 

maybe silicone or epoxy putty? OH! I know! MIGHTY PUTTY! /DesktopModules/ActiveForums/themes/hybrid//emoticons/biggrin.gif sorry I had too.

 

time for crabs for the new mangrove island

Thats not true, Buoyancy = weight of displaced fluid.

 

Clearly I was referring to weight of the given object in a response to "it feels heavy"... OR, perhaps better said, just because something feels heavy doesn't mean it will sink. Conversely something light won't necessarily float.

Even then it does have to do with weight of the object.
It has to do with the weight of the given object in relation to the weight of the displaced fluid taking into account the density of the object and the density of the fluid it is in.

 

As I corrected myself already, I meant that simply weighing something (or getting a perceived weight) is not a good indicator of whether that item will float or not. In any case, we are going in circles saying the same thing over and over again. Being that this isn't a physics lesson, I didn't think the fine details mattered so much, but clearly they do. /DesktopModules/ActiveForums/themes/hybrid//emoticons/smile.gif Moving on now...

Sorry bud, it happens so infrequently that I can say something that makes me sound smart, that I have to jump on every opportunity!

yeah, it has the black pond foam on it. Great designs and painted with fiberglass resign and covered with sand. It looks great, but at this moment a bit unrealistic since it is more like an island.
I'm sorry but the visual of putting it in the tank and it FLOATED just made me laugh.   
I hope you find something that makes it work.  I'd love to see a picture of it.

 

im having the same problem. so help would be appriciated. and my tank already has water ij it

 

i would say either find a way to silicone it to the wall or find a way to attach more rock to it. my rock wall was mainly rock not a whole lot of foam. you could zip tie some big rocks to it. or epoxy them

 

k well i was thinking of using pvc pipe and as i cut the hole for it i noticed it is hollow so im hopefully going to fill it with sand or maybe something heavier? and ideas on that?
