Kaesh sump combined algae scrubber

[Kaesh]

I would increase flow on return to raise flow. You'd be moving more of the display water over it instead of water that's already passed over it. But that's how my brain works. Is that a poece of hose split and placed on the edge of where the water is flowing? Maybe remove it to lower that edge to create more flow. Or would flow reamin the same just lower in that box?

yes its a one side cutted hose the water flows under the hose and over inside its groove, and make the water evently flow down, equal on each square cm. the flow now is 2000L/h on 50cm wide screen. The hose holds the screen btw.

So is that pipe something similar to drain tile?

Not similar, it is And its really usefull and simple idea.
BTW, i cleaned my screen :

This scrubber thingy is still awsome (i dont use skimmer, just weekly 15% water change)

Dinner time ? Looks like a substantial harvest. I would like to know how to process this to make proper, high quality fish food. Looked at the Chinese paper method of making nori but details are a bit sketchy. Anyone got any ideas ?
