Which AI Axis will fit in Waterbox 20 Cube for return pump

[bubbgee]

I am looking to replace my Sicce micro with a better pump but I cant seem to find something that will work as a better return pump. I was thinking of the AI Axis but I am not sure which one would work (the largest I can fit in there).

Is there anyone who has been successful upgrading to AI Axis on their Waterbox cube?

Axis 40 would be the right size and flow rate. I don't have one though, so I'm following this thread.

I recently installed the Axis 40 on my waterbox 20. Fits perfectly. It's a lot of flow though, mine runs at 50%.

How noisy is it? Any “humming” sound?

I know it's slightly bigger but I have the Axis 40 in my WB 25 and it not only fits but it is dead silent. All I hear is the trickle of water when it goes out of Feed Mode.

Mine is dead silent too. So far I'm really loving it.
