After the acid bath, I let the rock dry out for a couple weeks. Now on to aquascaping!
I like this final layout but keep in mind that I didn't have any fijicrete, so the arches are temporary. They are just holding things together. I am going for three islands. Mind you, the arches are starting to grow on me. The way it sits, it's about 70" long. Should fit well in the temporary 79" long tank.
They are based off a big rock at the bottom, with a 3/4" PVC support that I drilled into the rock. This allowed me to brace most of the pieces so that they are stand-alone structures. There's a couple pieces that will need to be fijicreted or zip tied into place.
