Hot glue as aquarium adhesive
Has anyone used hot glue to adhere decor to an aquarium, specifically an acrylic aquarium?
My wife bought some resin faux stone shelves that she wants to put in the 400g acrylic aquarium. Normally, I'd use silicone to attach them, but they weigh just enough that I'm afraid I would have to sit squeezed inside the tank for hours until the silicone set enough to hold them. So, we thought about using hot glue, or possibly super glue. However, we want to be able to remove it in the future if we ever decide on a decor change. Also, chemicals leeching into the water from the glue would be a concern.
If anyone has used either of these glues on acrylic, I'd be interested in hearing how it turned out.
