Still a little yellow... maybe less hours.
Yes, i wil reduce the light hours back to 9 hours on today. That is from 13 down to 9.
Have been thinking if this type of scrubber differs from f example the SM100 type scrubber when it comes to need for light hours. The screen actually never have total darkness like the screen in a SM100 type of scrubber. The screen have light from the leds during the night, and when the leds is off the screen actually have daylight from room an windows.
Any opinions?
Don't see any harm as long as the light is not much stronger than a full moon. There is a limit where the photosynthetic "dark cycles" are triggered, but I guess there's only one way to find out ! Keep us informed.
Hmm, i think the screen is growing slow, the aquarium is looking great though :)
The screen is growing green at the longest distance from the light, just the same symptoms as with my waterfall scrubber that used the same led light. I had green hair alga in the bottom of the scrubber box in the waterfall scrubber.
Well, the light hours is now only 9 hours on, i wait and see.

Hello!
Here is another update video of 10 days of growth.
The growth is now longer and more hairy green color.
The lightning hours is now only 9 hours on and i have also reduced the watts to the half effeckt, i am now using only one led unit.
Dont think my screen like lightning at all :) maybe just daylight would have been enough :)

One 3-watt?
No, it is one of these units, without lenses. It is labeled 3x3W, but i dont think the real effeckt is more than max 3x1W, i tried to measure the effect and i think i remember the total effect was less than 3W.
The distance from the led unit to the top of the screen where there is most growth is about 5 inches, and i am also using a light diffuser in front of the led???
Cant really figure out this, i am using mutch less light than for example Floyds test scrubber and i still seem to have too mutch light?

Are you using the driver that they sell with these or have you bodged your own. They reckon output is almost 3 watts ( I've also looked at these ) if you think there rubbish I won't bother !
That's the problem... the LEDs are too close together.
