    Hello, new to these forums, just been reading about scrubbers, decided I wanted one for my 90 gallon fish only tank. Also wanted to put my design skills to use, so I came up with this:
    Designed up in CAD, the box is made from acrylic. The blue pieces are to hold the LEDs in place and will be 3D printed.

    Testing the LEDs, 10-660nm, and 2 Royal BLues

    Screen is a 4x6" screen 6 3w LEDs per side powered by a LPC-35-700 meanwell driver. Water will be fed with a Quiet One Lifeguard pump, which should do enough GPH for the 4x6" screen. If i did my research right, it should be enough for a 2 cube/day tank. I'll post more pics as I build it. Comments/Suggestions?

  2. looks impressive, but 4x6 is a bit small for a 90 gallon system. Turbo should weigh in he is the expert

    It's not about the size of the screen so much as it is the amount of feeding. I regularly recommend 4x6 (that's the L2 screen size) for a 90g system.

    My main question is about the heat sinks, I don't see those anywhere in the pics, what are you using @joleobee?

    a 4x6in screen is 24 in^2, 4x6in exposed screen lit from both sides is 48in^2, for some reason I thought 2 cube was 12in^2 lit from both sides or 24in^2 from one side?

    You are correct

    The feeding-based sizing rule is 12 sq in (length x width, not surface area) lit on both sides. Effectively, this is 24 sq in of surface area, but using both terms (size and surface area) generally leads to confusion at some point, so I leave surface area out of the discussion. Also, a single-sided screen does not equal the scrubbing power of 1/2 of a double-sided screen of the same size.

    Weld on #4 and some clamps, pretty easy to work with. Stuff sets pretty quick and cures fast.
