Welcome.

Can you increase flow? If now, maybe you can reduce the width, so that the same water has less area.

So, this runs off an overflow tank. It is a bit short on flow, won't be a problem now but as you get thicker growth you'll get relatively lower flow to algae area. This turns the algae brown. Should be easy to increase it though shouldn't it ?

[Kaesh]

Yes the water comes from the main tank overflow, no extra pumps just the water i have returned. now my pump is on half steam, so i can increase the flow to double or if it will be not enought maybe an extra pump.

And santamonica -> thank for u to create this site, and let us know how its works....it awsome stuff :cool:

[kerry]

Yes, make it flow more.

[SantaMonica]

Happy to see it working for you.

You could also put a pump in the lower chamber to the upper chamber if you don't want to increase flow through the tank, that would just increase flow over the screen and that is the main point.

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?

Hello SantaMonica can U give me an advise?
Need i clear the screen from algae? Its one mounth old, and i got a very thick algae growth. The water paramteres are excellent, nearly zero nitrate and phosphate.

Yes it needs cleaning, before the dark growth blocks too much light from the screen.

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?

[Kaesh]

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 ?
