Enclosed WaterFall Scrubber

[uruguayanreefer]

I built an Enclosed type scrubber in hopes to prevent excess evap and potential salt creep.
I made a 1/4"x9"x12" acrylic box with a 8x11" screen. 5 3watt 660nm are driven by a 700am constant driver, all mounted in an old car amp case. I used a Mj1200 to pump water thru 1/2" pvc. im only looking for 35gph across the screen so i think the pump is fine.

It will have a 12 on 12 off light schedule unless someone here suggests otherwise. I hear this type of algae likes to grow when the lights are actually out.



Let me know what you guys think of my build!
Im always open for suggestions on improvements as well.


Thanx

Isnt the flow ideal 35 gph per inch? So 280 gph. I built a similar thing for my scrubber, but its open bottom. I just mounted it so that the bottom is just a touch under water. I also made the pump connection (using a bigger pump) rigid so its free standing (there is a pvc leg on the other side).

Yes, 35 gph per linear inch of screen; give or take. I 'power' mine ditectkynfrom the tank overflow, so no extra pump capacity required.

Im sorry when i said i was lookig for 35gph across the screen i meant per inch. The box sits on top of my sump the pvc "leg" u see is the drain line that run into my sump

And I would have feed it off my manifold but I run a few things off it already. Light and mj1200 are timed the same.

Already getting some growth

Never tried anything like this but will the aluminum, if it is aluminum, corrode over time?

My scrubber is pretty much the same as yours, and it seems to work great. It's an acrylic box sitting on top of my sump, fed by the main overflow.
