I am not sure that I should recommend this as a course of action as yet as it is early days and problems may still develop.

From one of your earlier posts I see that you do not use the Fluval tubing as it "reduces flow by design". (I feel you my be right).

I would double check your hose sizes if this is likely to cause you an issue.
Sorry, my bad - I'm using 5/8" clear aquarium tubing ~16-17mm equivalent.

I kept the Fluval tubing for the intake because it was an easy fix and disappears on the black background. I used to use the clear tubing with the lily intake till I broke it. The corrugated Fluval tubing is a crap magnet - it's flexible, and necessary if you use their intake plumbing but otherwise not optimal, IMO - smooth tubing is aqua dynamic.
