I wanted to spice up one of my glass decorations in my tank by gluing on some stones that came out of my old tank. but would it be ok to hot glue them on there or should I use something different and how should I disinfect the stones?
I wouldnt use hot glue. there is so many variants in the making of it even though the base is usually a polymer some of the additives in some of the hot glues they add to make different setting times and structures of the crystals it forms that bond it form new bonds and new polymers some of which will decompose and release nasties into your water. Definitely stick with Silicone
Or maybe as macca said ^ ^ I Got halfway through typing my first post and had to dash n take the gf to work... came back, finished typing, hit reply and there was a new post haha
