When the aquatube is mounted horizontally with a flush jet also mounted horizontally in the center, the tubemeter can't be mounted vertically (perpendicular to the water surface) without bending it a little. Bending it just makes me cringe.
If I remember correctly though, the YouTube demo for the aquaero also shows a tubemeter mounted in a slanted position with a aquajet. It appeared to be bent as well.
Maybe I should just forgo the aquajet?
