building rock work
 

How the F do you guys get your rockwork structures to stay together????
Ive tried everything over the 10 years or so Ive been in the hobby and apart from just stacking it in a huge pile it seems to fall apart in 3 months to a year.
Ive always used acrylic rods. tried epoxy, silicone along with them and no matter what they fall apart over time.

of course after they been in the tank for a year I gotta breeak off the corals and pull the rock out let it dry redo it and re cure it. usually leaving my tank looking like crap for a few months.

would pond foam work better? i seem to see mixed reviews online.
HELP!!!!!!!!

Drilled the rock and used acrylic rod for the larger pieces and towers. Smaller ones are either replaced in a stable position or use a pile of epoxy.

Im going to try this... http://www.fijireefrock.com/product/fijicrete heard good things as long as u work fast

Figicrete is awesome . Tried it a couple months ago on latest build & works good !

Zip ties my latest floating rock work is all tonga and zip ties. Once coral starts growing you won't notice it at all.
