Ah.... I think I see that in my head. Wish I didn't toss my old horizontal tray I had. I would try what you got going.
Seems I had more copepod production with the horizontal.
Hey Garf:
I am making something similar, but it is not a waterfall. It will be a plastic container that holds the screen fully submerged about an inch under water and the return from the sump will have a spray bar pushing the water through it with the light above the screen...
Cheers....
Well, in general it's a bit of an old concept (horizontal scrubber). It seems as though folks were encouraged to have the screens out of the water, making the flow very thin (and fast).This obviously restricts algae movement but provides more flow. I might throw the return from the skimmer on it, opposed to the flow of the vertical screen, just to add a load of swirling goodness.
Feeling pretty damned smug TBH not a huge harvest but this is just 1 weeks growth (second week from start up)
thats how my first scrubber grew, i floated it on top of my cpr fuge then i changed a bulb and it crashed for some reason into dinos
nice growth!
whats your photoperiod?
and what your consideration about led and CFL?
looking the picture that you posted last page, looks like CFL is doing better...
I think the difference is purely that the LED is directed to the waterfall screen, not the horizontal. The cfl light at least partially lights the horizontal, although nowhere near what it should be.Hopefully gonna get it fully lit and compare the waterfall and horizontal side by side.
Edit - 18 hr period
you only do 6 hours off?
Yes. Always run like that.
