I love columns and arches. I want to cast a small column to let gsp or xenia take over. But I spent enough molding my 10lbs. I used instant ocean epoxy.. it gets expensive. Use jb waterweld. It's half the price same effect/reef safe. I have repaired catamarans with the stuff when I did guided tours in Alaska. So I don't think it will break like people claim epoxy. I did tack my work together, blew it off first. I didn't want to be another horror story of a breaking arch. Can't wait to see your work; edit add here... I used 2 sticks of IO epoxy before I switched and used 2 tubes of jb waterweld to make it a solid structure. Check my build if you wanna see the 2 arches I made with the 10lbs. I don't wanna photo bomb your thread. Give me motivation for my next rockwork. The tank ironically enough is going to be a 40b.Have the rock, and a few idea layouts for a 40g breeder. Mixed tank but no SPS, figured I would go with 2 main scapes with islands. looked at a lot tank layouts. not decided yet, NSA is what I'm looking to do but don't want any tree looking builds. No problem with breaking up the larger rocks since they are to big for the tank, Going to use E marco mortar to bond them. lets see your ideas.
I have mine, but open to new ones. I do know that in time the scape will be covered in corals.
