My new setup ATS

[alum]

container: (h)30cm x (l)40cm x (w)20cm
screen : (h)27cm x (l)34cm
pump 2000 L/H connect with air

led : white 3.2k x 6
red 660nm x 8
blue 445nm x 3

something missing ??

Don't know if those whites are going to do you much good, but we'll see. The plastic material looks like a good diffuser, but at the distance from the screen it might be knocking down the intensity too much. Try it and see!

Do you meant is perrish wheel light or merry go around ? LOL
this white leds came from the old ATS before.. still experiment sir! LOL

The white is 3.2k warm white.
I use them because I have no red light avaliable from now.. I think you are right the light too strong, algae going whiten..

I will add resistor to white leds to reduce intensity.. see what it will be..

Not too intense - the whites are the wrong spectrum. "K" ratings for LEDs are meaningless - they do not compare to CFL for our purposes. LED "K" ratings are only there for marketing purposes, aimed at architects and lighting designers who wish to replace less efficient lighting with LEDs, but want them to look the same.

For growing plants/algae, you need deep red and far blue. This corresponds to 660mn Red and 440-455nm blue. Anything else is just filler, and is likely wasted energy.

Warm White LEDs do have red in them. But that's the only part you really want.

I would like to change it but after Installed UV sterilizer my ATS and UAS work down and now my refugium grow a little bit faster that's why I will wait before to change white led into red ones.
Now I just turn on the red leds only..

Fixing project :

changing all white leds into red leds, could be like this.. :


still waiting for delivering order..

[alum]

Don't know what missing here.. here the result after chaanging warm white led into red leds.




But I will move the screen closely to led between 10cm now from them.
might be better? any suggest ???

A few questions:

1) What is the screen material?

2) is it well roughed up?

3) how long has this screen been running?

It doesn't look bad, if that's what you're worried about. Do you have pics of growth from before you switched the LEDs?

1 & 2. its plastic and already roght enaugh.
3. I think its abaut 2 weeks ago.


I just compare what I've got before in my UAS .. I've got hair algaes, like this : http://algaescrubber.net/forums/show...m-in-Indodesia

Looking great that I had before.... the question is can I get the same result with my new ATS now ?

and I've been thinking abaut what you said before, the container wall will deffused the light.. so then I try to cover almost whole wall container with black plastic and add 1 fan, see what it can do..

anyways thank's a lot. I will post later the result.
