Additional information on the tank size, water test parameters and critter population would help but I can say that 7 days of operation is way too short. I would also add that one of my early ATS...
Cracker, I use three on a one sided 5 x 12 (w x l) screen and yesterday's harvest was 240g of wet algae on a 10 day growth cycle. Edge to edge 1/4" thick green mat. My lights are 2" from my...
Cracker, how many of the expression LEDs are you using currently. I run three on a one sided waterfall and they grow lots of algae. Mine are oriented lengthwise on my 11" long screen. What are...
I started mine with a fluorescent while waiting for my LEDs to arrive from Shanghai. Stow start but way better than doing nothing. I chose a narrow and long screen (5" x 11") waterfall on this...
I use the same bulbs for a small scale horticulture project except I removed the lenses and got a much broader list spread. They definitely produce a lot of light And the price is right. They have...
I have grown great algae with fluorescent bulbs but the space they consume was a problem in my space restricted sump. The LEDs generate little or no heat, can be configured in almost any design and...
Red (660nm) are apparently the most productive in producing algae. I started with fluorescents and switched to LEDs, no comparison in terms of production. LEDs also take a lot less space and are...
Maybe the test results are false because your algae growth is extracting the nutes from the water column. It's there somewhere if you are growing on your glass that rapidly. Your screen also...
What parameters is your ATS working to address, i.e., NO3 and PO4 specifically? This and structural info such as distance of lights to the screen will help the smart ones address your situation.
My current ATS setup, my fourth version, is a single-sided waterfall on a 20 degree angle with a 5" x 11" (w x l) screen using an MJ900 pump (12" head) and three Expression LEDs. This new setup took...
I believe you will like the Expression LED lights. I have been using them (3 on a 14x6 screen) for well over a year and they are very sturdy and well made. Following and good luck.
The lights are three 9w strips fro Expressions LTD. The white plastic screen tray and light holder are silverware trays from Wally World.

Yes, I see the turbulence factor, similar to the tank water surface exchange process. Anyway, here is my current prototype. An ATS is a tinkerers dream!

My ATS is horizontal with about a 20 degree slope to the drain. It sits on top and perpendicular to the sump. The water feeds via a Rio 600 pump to a 1/2" PVC pipe drilled with 10 1/8" holes...
I have three of the Expression, LTD led lights on a 5"x14" 1-sided screen ATS. My ATS is a hybrid waterfall unit sitting at a 45 degree slope. I harvest 100-120 grams of wet algae weekly. The...
I had two and added one more on a 11 x 7 upflow screen and I am vert pleased with their performance. I harvest 100-120 grams of wet (squeezed) green algae every 8 days. They are a bit long at 12"...
Santa Monica, could you please detail a bit of information on "sliced airline" and manifold air feeds? I know I have seen something on airline slicing somewhere but can't immediately locate. Thanks.
I am curious as to why a waterfall type operates on cascading water but submerged upflow types operate with bubbles. Why doesn't an upflow scrubber run well using a pump to push the requisite volume...
I used a short drywall saw and wrapped the screen over a slightly curved surface (bucket) and worked it with slight pressure. I used a heaven grit sandpaper the break the shine. I am working in a...
PeterFranc, how many of those strip LEDs are you using on what size screen? I am impressed with your growth. I have two of the same strips on a 10x6 up-flow ATS that I have just started.
What's weird is that my order shipped a day or so ago and today the site evaporated. Gone. Nowhere to be found. Oh noooooo!
I have also ordered two to convert from CFLs. I also have some spare 6w stunner strips, 445 (2 each), 453 and a 403 UV. Would adding any of these be of any benefit to growth or would they be of no...
Morioka, I am interested in the performance of your LED light. Still doing well? How about fan noise? You still happy with it? I am using CFLs and need too shrink the footprint of my ATS. thanks
