Posting this from my phone so adding pics right now won't happen
I built a enclosed water fall scrubber
12x9x1/4" acrylic box
11x8" screen
5-660nm leds
700ma constant driver
mj1200 for flow
and I used a old amp for a heatsink
I will post pics when I'm at the pc as I'd like to get feed back
I started the scrubber this morning on a 12hr on off schedule so I should see growth in a few days
