Glad to hear that they would work when wet. I guess I'd use one then so that I can water back in fast and prevent my plants from drying up. Thanks a lot!
That's cool, I haven't heard of coral glue yet. Sounds handy if it still cures while fully submerged. I'd use super glue for now but I'd try to get my hands on a coral glue for future projects/problems. Thanks!
That was my original plan since it didn't float. Problem was it was swaying a bit with the flow from my HOB, and the epiphytes that I stuck between the gaps came loose. I think it's necessary to glue it back if I want to keep my current scape.
