Air flow VERSUS water flow

Post by kokobongo »

Hello. I would like to use 100mm diameter tube. You recomend about 60 liters per minute (Secoh JDK 30). Will I get bigger water flow if I use higher amount of air? Lets say 100 liters per minute? Or there is some threshold where water will be just oversaturated and airlift will not work efficiently?

Also is there some graph with test results?

Thank you!

You are right, adding more air will improve performance but it will not be efficient with a 100mm tube. Please refer to our testing to see what combinations work best:
