Since the aquarium glass is fixed with a kissing rubber, the air stone will not move around in the aquarium like a lightweight conventional product. 3. Unlike traditional adhesive forming air stones, it will not break down or break after long-term use. 4. In addition to the air filter of the air pump, the air diffuser also removes debris from the air injected into the aquarium. 5. As with traditional adhesive forming air stones, it is difficult to decrease the breathability that can occur over a long time. 6. Even if the air filter is degradated due to dirt or degradation due to long-term use, you can replace the air filter (sold separately). 7. Kissing rubber is an Aheim standard replacement part, so it is easy to obtain even degradation.
