We are looking into how we can further improve on the design to have a better air flow.

The L joint caused a reduction in air flow and therefore when it is placed even at 5cm depth as instruct in the manual, the air flow might not be too signicant unless it is place less than 5cm depth which is near to water surface.

The function of air venturi is to create water disturbance to allow more oxygen exchange between the water surface and the environment in addition to the water circulation that is created by the filter.
Thanks for the answer. But right now do we leave it 5cm underwater surface or do we put it nearer to the water surface till we see bubbles?
