That build has a bottom drain.
So, What gives the 3D hair growth? Or would you get that even on a simple nonacrylic setup?
There are 2 drains in my scrubber, originally they were both up about 1.5" off the bottom (male/female threaded fittings with o-rings on either side) but when I put on top of that tank I took one off, so it drains out the hole and then when the growth fills up the high drain starts.
The 3D growth is best achieved with a closed-bottom / drain design, but I would think you would be able to get some 3D growth just by putting a piece of acrylic on either side of the screen, and within say 3/4" of the screen or so, but you would have to hold the 2 pieces together at the bottom corners too. Once the algae grows thick enough to come in contact with the acrylic, it will trap water and little air pockets.
You can see it in this video, really well at about the 0:45-1:00 point

I think people are a little crazy about 3D!
First it's movies, then your TV and now my algae scrubber. Let me guess I need another pair of glasses for this one too??!!! Lol
3D growth happens naturally really. My open scrubber has started producing 3D growth. With plenty more fixes and adjustments needed I think it's just getting started. I will post pictures when I can.
Here's today's harvest - 3rd week in a row of stellar growth!
I've had this one running for about two months now. It's made from a 14 gallon rubbermaid container.
It's on a 180 gallon tank with an 18" x 11" screen with 4 CFL bulbs on each side. It's fed by a separate pump and then empties into the sump through a hole in the bottom.
Nice build, good example of what you can do for very little cost.
Looks like a single-sided scrubber. Have you been getting good growth?
There are lights on both sides, you just can't tell from the pic. I couldn't get a good picture under my stand.
I haven't weighed what I scrape off, but it appears decent. It's not 3D or anything. My N has stayed at 0 and P is also undetectable both on Salifert kits.
That makes sense, that's the way I understood it. An acrylic Algae turf scrubber is the next piece of equipment I'm investing in. I'm a big fan of natural (well non-chemical) forms of filtration/supplementation. The less chemicals and supplements I can use, the better IMHO.
The next piece of equipment I'm adding is a Santamonica 100 model turf scrubber. I love the fact that it's clean, all in one, and isolates the light from the unit.
