X JBL Aeras Micro Ball L
Ball shaped airstone
- Made of a quartz sand mixture with extra-fine pores for super-fine air bubbles (hence the name, "micro").
- Ball-shaped air stone of 40 mm diameter.
- Specially suited as an air stone for garden pond aeration (see also JBL Pond Oxi-Set and JBL Floater + AntiKink).
- In the aquarium, the air stone's own weight keeps it on the bottom without any additional weighting.
