Review on 🐠 JARDLI Aquarium Air Bubbler Glass Cup - Bubble Sputtering Protector by Michelle Moore

Bubbler glass tumbler works mostly as advertised but would benefit from a second version. The mounting points are too high so the vent stays very close to the water level when you keep the tank full. Also, the breathing hole that allows air to escape is too small, causing the system to "gurgle" instead of breathing. A small amount of water squirts out. It's much better than a regular bubbler, but doesn't completely remove bubbles.
