Adding more to aquascape in tank

[FDchase]

So I built my aquascape and am very happy with it. Although I would like to add a little arch and another branch I had built to help hide the new filter. I tried setting one piece with fluval 2 part epoxy and it fell over after 2 minutes. Anyone have suggestions on how to set more rock without taking rocks out of the tank.

I don’t have any idea other than acrylic rod and drill, I tried epoxy never held.

That sounds like I’ll have to take the rock out. All my rock is currently held with superglue and epoxy. Just don’t think I’ll get it to work underwater.

There is new product coming out that was introduced in macna in several weeks that works under water. There is thread on it in reef discussion
