So I made an attempt to make some DIY dry rock that seems to have come out a crumbling mess.I have some frag size pieces that will be ok. I'm wondering if I can use the crumbled sand/cement leftovers to be reused as part of the base for a new batch.Since it's aragonite and cement it should be ok as new filler.I used No salt in this batch and don't plan to use any in the next.Sound ok?
