ok. today was a lot of work.. and pain...
First, I disassembled the screen again so I can make four modifications:
1. Replace the clips holding the screens with an inner tube to force a more uniform distribution.
2. Plug up the ends of the top tube to avoid the water running down the vertical pipes.
3. Add a lower pipe so I can stretch the mesh to create a more uniform flow.
4. Rough up the mesh.
5. Create a light shield for the top slit to avoid algae growing into it.
Ok.. so here is the mesh removed:

and here's the screw that holds the frame in place

Here is the clip holding up the mesh

This allows the mesh to be pulled out

I replaced the clips with 1/2" PEX pipe. The idea is that this will force the water to flow further down the 1" PVC before flowing down to the mesh.
<a href="http://s1062.photobucket.com/user/karimwassef/media/C78605CD-E21E-4C59-A7CB-6EFF4F4B2D0D_zpsv0kev2ti.jpg.html" target="_blank"><img src="http://i1062.photobucket.com/albums/t496/karimwassef/C78605CD-E21E-4C59-A7CB-6EFF4F4B2D0D_zpsv0kev2ti.jpg" border="0" alt=" photo C78605CD-E21E-4C59-A7CB-6EFF4F4B2D0D_zpsv0kev2ti.jpg"/></a>
I used epoxy putty to plug up the ends inside the elbows behind the PEX. It's hard to see, but you can see it in the far end of the pipe.

Some of you recommended I try fishing line, and since the holes are now offset by half a step, this is a perfect opportunity to try it...
I didn't have mono filament nylon fishing line, so I borrowed my daughter's silicone line. It's like fishing line but it's rubbery and stretchy. She uses it to make jewelry like bracelets and necklaces.

I liked the silicone line so much I decided to change one of the four corner bonds in the middle of the mesh to see how it compares... experimenting...

Now it's time for the light shield. I decided to use 2" PVC with holes and slots cut to cover up the opening.

Now it's time for the light shield. I decided to use 2" PVC with holes and slots cut to cover up the opening.

Maybe feed the screen from both sides instead of the middle. Was having trouble with flow going evenly over the screen. Now water flows in from both sides.
View attachment 352183was able to get a more even flow. Sent from my SAMSUNG-SM-G900A using Tapatalk

I agree. Feeding from both sides would be more controlled. I got it working, so I'm satisfied with it for now.

I'll start on the lights now. I think I'll move the CFL closer ? Still need to migrate to the 200W bulb and get the 100W LED assembled.
I have this temptation to add massive DC fans to blow air against the screen. It just looks like a perfect swamp air conditioner ... The LEDs will need some cooling so I might combine the two. I'll try to resist, but three powerful DC fans in a row would be awesome...
Here's the docu-video version

I like to experiment. The plumbing is creating excessive shadowing so I'll move it closer.
I'm looking forward to comparing the front CFL growth and the back LED growth... should be interesting.
I'm also going to turn my tank dark for a few days to see if I can't accelerate the growth on the screen.
Since I'm sharing, here's my floating sump ATS

Try increasing he spread of light, I was using 2 par 38 bulbs on each side of a 13"x10" screen all the bulbs were 36 watt 9 red/ 3 blue led. I am now using a landscape 30 watt LED flood light which has much better spread. ( red to blue ratio is 4/1
The original bulbs had a spot light effect, it was strong at a certain point but nothing between the lights

Thanks. I'll play around with the lights.
Any other ideas on making it better?

I don't have a spotlight. My current light is a large horticulture reflector... I can change the shape of the wings to change the distribution.

In case anyone is curious why I'm pushing my ATS builds... I live on a lake and have an insect invasion due to a semi-open tank. And I have this strange "black algae"

Ok. Lights. Here's my LED build:
starting with Aluminum flashing 20" x 20" ~ $1.50 and wrap some white duct tape on the edges to avoid getting cut ~ $0.50
<a href="http://s1062.photobucket.com/user/karimwassef/media/49529016-FE8D-46A3-AEA5-CE632BD53834_zpsinkudpwb.jpg.html" target="_blank"><img src="http://i1062.photobucket.com/albums/t496/karimwassef/49529016-FE8D-46A3-AEA5-CE632BD53834_zpsinkudpwb.jpg" border="0" alt=" photo 49529016-FE8D-46A3-AEA5-CE632BD53834_zpsinkudpwb.jpg"/></a>

and line up the 7020 rigid LED strips ~ $15 (these have sticker backs)
<a href="http://s1062.photobucket.com/user/karimwassef/media/41DF0A17-2158-405D-8B91-61A3E46D376D_zpsxzbexouc.jpg.html" target="_blank"><img src="http://i1062.photobucket.com/albums/t496/karimwassef/41DF0A17-2158-405D-8B91-61A3E46D376D_zpsxzbexouc.jpg" border="0" alt=" photo 41DF0A17-2158-405D-8B91-61A3E46D376D_zpsxzbexouc.jpg"/></a>
cut out the duct tape to get a solid interface to the flashing.

line it up with 12V power supply ~ $25 and a fan $10 and use my PAR sensor a foot ahead of it...

I wired up a couple of temperature sensors at the center and the edges...
<a href="http://s1062.photobucket.com/user/karimwassef/media/03799cd2-9b1f-4c5c-96aa-334cb4e7833d_zpsksyox3st.jpg.html" target="_blank"><img src="http://i1062.photobucket.com/albums/t496/karimwassef/03799cd2-9b1f-4c5c-96aa-334cb4e7833d_zpsksyox3st.jpg" border="0" alt=" photo 03799cd2-9b1f-4c5c-96aa-334cb4e7833d_zpsksyox3st.jpg"/></a>
After about an hour, here's the result - the temperature rise in the middle is 14 degrees F. At the edge, it'd 8 degrees. Max temp is 100F in a room with an ambient of 86F. So, the design is sustainable.
Here's the fun part -
At ~ 110W, this setup has a PAR one foot away on center = 318!!!
In contrast, my 125W grow CFL (it's a year old) = 92!
That's 3.5 x more PAR from the LED.

After about an hour, here's the result - the temperature rise in the middle is 14 degrees F. At the edge, it'd 8 degrees. Max temp is 100F in a room with an ambient of 86F. So, the design is sustainable.
Here's the fun part -
At ~ 110W, this setup has a PAR one foot away on center = 318!!!
In contrast, my 125W grow CFL (it's a year old) = 92!
That's 3.5 x more PAR from the LED.

So the light cost $17 and the power supply and fan were $35. So $52 for 110W LED at a PAR of 318.
The CFL reflector was $33 and the bulb was $23. So $56 for 125W CFL at a PAR of 92 (old bulb - for full disclosure).
I'll put the new 200W CFL ($20 bulb + $7 adapter) tomorrow and compare. So $60 for 200W CFL at a PAR of ... TBD

Is it just me or is the mesh already getting discolored after 24hrs with the CFL?

It's more brownish in the middle areas of the sheets (where I roughed it up more) and bluish at the interfaces (where I went lighter).

Decided to hang the LED square

Left the CFL up for reference (for now)

It's ~ 10in away and screen PAR is 400

It does look better and more uniform. Of course the 4x increase in PAR doesn't hurt.
Barrier accumulate salt creep and reduce light, but then again, that would be on the LEDs otherwise. I'll try and contain the spray another way.
