440L ATS design with 660nm led

[Floyd R Turbo]

Dontt use RB. you want lots of red and very little blue. Ace25 did a build with 460nm RB and didn't grow anything. Currently he runs all 660nm red. I'm getting custom fixtures made to do a spectrum/growth test.

ok that makes little sense that the RB led didnt make growth... But on the other hand if you look on most plant ligth it looks more red than blue so maybe that makes sense after all
look at these two led"bulbs" they look promising...

and this article concludes that it IS the red light spectre we want for the growth..

Nice info! Interesting that the first lamp lists ATS as a use.

new plans!
I have bought some 3W led with 660nm... I have red a lot in here about the nm in the leds. I hope this will give my ATS to come good crowth!

Update: I have now arranged the red led on each side... It has been so for a week now.
The algae for fist cleaning are very light brown on the ATS or nothing almost...
Im not sure I feed enough, I feed one frosen cube each day, should I feed mere? I Have a 440L.´s tank...

this led scrbber has run for two weeks and the algae are starting to grow but not in the middle???
Is it because the light is too strong?
on each side I have 10 3W led in the 660 spektre...[attachment=2:t7noh471]lampe.JPG[/attachment:t7noh471]

More flow. More iron. Or less hours.

Thanx for the fast response!
Could I feed more? I only feed one frosen cube per day...

the tank is 440L. and the pump is a 2000L/h pump that should be enough for 22cm length ATS...
