Not sure that a 5mm wide gap between the cylinders is going to allow quite enough space for the screen and any significant amount of algae growth. I think I'd try at least 15 mm there.

Further thought,
How about if the water entering a circular chamber could be made to swirl round it, perhaps by having a 90 degree bend in the inlet?
That might create a fair bit of flow over...
Looks good.
Build it, see how you get on.
But how about building one from two concentric acrylic cylinders?
That, if the flow could be controlled, would create a chamber of running water...
A bit like those overpriced phyto reactors you can get

I suppose it might be useful as a space saving idea in certain...
