JBL Proharu Universal is a black universal adhesive and bonds almost all materials together (except PP and PE plastics) - The adhesive can also be used under water as it uses moisture to cure.

It can be used, among other things, for leaky aquariums, to fix decoration material or to secure stones against tipping over, as well as to fix different materials to each other (e.g. wood to glass).

JBL ProHaru Universal is non-toxic for the aquarium inhabitants and odourless

It is advisable to switch off the filter for the duration of the work when the aquarium is in operation.


  • Adheres to almost all materials
  • Can be used during operation, even under water
  • Non-toxic for aquarium stock
  • Enables complex hardscape designs
  • Also sticks mosses & ferns to decorations

He doesnt hold anything. I wanted to glue driftwood and stones, but nothing came of it. Glue does not hold objects. He just messed everything up. Plants dont stick either. (read more)
