Hobby Vulcano diffuser stone

The “natural diffuser” that not only supplies your aquarium with air, but is also decorative. Each lava stone is unique and emits a different number of bubbles.

Each Vulcano diffuser stone is a hand-picked one-off made from genuine volcanic rock. Due to the internal hollowing of the rock, the air seeks the path of least resistance and sometimes has more, sometimes fewer air outlets. This means that larger air beads can escape even without a powerful pump. Each stone is individually processed and tested. The flattening on the underside makes it easier to set up.

Size: approx. 11 x 8 cm
