1st UAS scrubber

I'm not having much luck with this so I'm going to do a 2 sided waterfall. Using 2 cube a day, would it be 6x4 with 12w on each side? Also can you have too much flow?

Size and light looks ok for 2 cubes. You don't want the flow squirting all over the place, but good flow is important when the screen really gets going. As long as the water forms a continuous sheet of flow from the bottom of the screen it is deemed adequate.

So a eheim 1000 would be ok? Should I use 16mm or 25mm pipe

Would these be ok to use? http://www.ebay.co.uk/itm/12W-LED-35...ht_4838wt_1301

Can also get these with all 660nm bulbs, do you think up they would be any good?

Those are ok for a small screen.
