gravity stack

[Geoff_Poz]

I have read a lot about gravity stack rocks "crashing". I have seen threads about rod support and glue gel support. My question is...I have used gravity stack method on my tanks, and has anyone seen any long term permanence in this method? With the growth of Coraline algae and/or other growth, do these rocks eventually "glue" themselves together?

I would say it is possible for rocks to fuse together, like they do in the wild. However, I doubt it is probable in most home reef aquariums. Only time i have had rock work fuse together it was with SPS encrusting it together not coraline. Just my experience. Good luck.

Sponge growth can help it hold together over time but not as strongly as sps growth. I'm not sure what is meant by "gravity stack method".

I've had corals grow from rock to rock and help solidify the stack. BUT it has never been strong enough to solidulify the stack. I've seen the whole encrusted base split like a fault line. IMO you Ned to make sure its well balanced or figure a way to support the construct.

I agree. Picking up rock falls is no fun.

I used acrylic rods and am happy with the structure. I never liked a heap of rock.

Ok, you guys got me. What is gravity stack? Sounds like I should ask someone to pass the syrup . If it's piling rocks to balance, provide swim ways,caves and overhangs without rods glues etc. ,
I can do that and make it last longterm,8yrs anyway..

Yeah, that's what I was referring to Tom. Not sure if the original poster had something else in mind. Not sure what that'd be, but Avatar comes to mind.....

MMNN...syrup. Thanks for all the replies. Yeah, I was talking about just using gravity to hold the rocks down/together without any other support. I guess the verdict is that a standard solid stack will be fine, but bridges/outcoves/tetering rocks would need rod support.

Yea Geoff...depending on the type of rock, you can get it to lock together nicely. Totuka works well because of all the nooks and crannies.
