not happy with the flow at all. It does flow 'decently' and the pump is around 250gph with a lifting capacity of 2meters. so it should be good, but im not happy with it. think my tube is too small tbh. its only 15mm ish.

It's the pump then, not the tube.

Can't have too much flow, as long as the screen is rough.

It should be very roughted up. Used the plastic Mesh that you promoted as best, and a hole saw. The growth is alot better these last days after increased flow. Hope to see results within a few weeks.

It has the look of a screen that is not getting enough light.
