ZAD-15 Air Stone
Material: PC + PP
Size: 12mm X 35mm
Color: Black + some blue sponge rings
The ZAD-15 air stone creates much more water movement with low pressure. It works very well, even with low-power air pumps. The ZAD-15 is heavier than other air stones, allowing it to be placed directly in the aquarium where it will sink on its own. This air stone is easy to disassemble for cleaning.
We also have cheaper air stones such as the ZAD-10 and ZAD-12.
