I've now removed my aragocrete rock from the mold. I've also taken the straws out. It wasn't too bad. I'm gonna wait a little bit before I begin the 6 week water curing process. Here are a couple of pictures of rock. I think it'll look fairly natural once the coraline algae and stuff grow on it.
I'm getting pretty excited to start plumbing. I still have to prime and paint the sump room. But I could get started on the closed loop soon after I order the oceans motions.
