How abaut separating the screen from the airstone?

I´m just starting to see growth in my LED scrubber but it seems to be yellow indicating strong light or reduced flow (despite I cover 4 sq inch...

If it is easy to build you can try one but I think It would be very diffucult to built/maintain. I see more potencial to changing bubble size but I´m not an expert.

One of the "advantages" of UAS...

Yesterday I moved ligh 1 inch away from the glass. Now covers all the screen.

After 2 days of growth I saw better green growth in the borders and yellow in the center so I decreased intensity...

Yes, 4 sq. inches is 5.3 x 5.3cm.

Ok, I´ll keep the spacing as it seems algae gets used to strong light. Maybe I´ll need to separate them a bit since I don´t use a difusser.

Thanks

How much shuold cover each led? Initial recomendation is 5.3cm x 5.3cm but I see some posts with areas 3 times bigger with 3W Leds.
I´ll wait to see I current configuration burns algae and I´ll...

I feed depending on nitrate level. From 1 to 4 times a day.
10 adult clowns and 200 small (1/1.5inch).
I also have a Deltec apf-600 skimmer, live rock and I dose sugar (wich I want to reduce).

Last saturday I replaced Light with 9 3W 660 nm LEDs and I added a small amount of algae next to the screen. The algae couldntt stay attached to the small rock because of the bubbles hiting them.
...

I have 20 ppm of nitrates aprox. but I will start increasing feeding as Scrubber algae starts growing.
The screen is larger than the Light I hace but the LEDs are 2 inch from each other so Algae...

I´ve built an UAS almost two month ago and I can´t see any green algae on it.

After 10 days I replaced the airpump to increase bubbles, then I replaced the 27W bulb with a new one. Then I changed...

Seller´s reply: Yes, you got the information is correct but it just for 1W led. We selling is 3W so the current can be increase to 700mA max.

Yes, I saw that too and I´ll ask the seller.

I´ve found 3W 660nm EPISTAR LEDs on Ebay :D

Specs:
"Wavelength: 660nm
Led chips: EPISTAR ES-SMBRPN42B 42mil
DC Forward Voltage (VF): 2.2-3.0V DC
DC Forward Current (IF): 700mA MAX ...

Thank you for your response.

I´ve found drivers that can manage 7-10 LEDs at 680ma (adjusts voltaje to maintain current). I´m still lookin for one with 750ma becouse the ones I found are just for...

I´m planning to give LEDs a try.
Looking for 3W 660nm LEDs on ebay I´ve found that 660nm may mean 650-660nm, 660-670nm or 655-660nm.

In the clorophyll graph is seems that 660-670nm will be...

Thanks, I´ll reduce hours but with the full setup.

I thought I read that less hours implies growth of brown algae instead of green in the ATS.

Yes, it is a good idea to prepare it for 100 gal to be prepared.

Would you use lights less hours a day or would you use lights just in one side? (the other side in case it is needed)

Yes, I was thinking in 85 W setup counting the full 85 Gallons. I´m curious if I can reduce the Watts and square inch since I also have a good skimmer that should "procesate" excess food.

I currently have an 85 gal tank (45 gal main display and 40 gal sump with caulerpa). I have a Deltec APF-600 skimmer.

I´m lazy cleaning the glass so I have alga in my tank and sump. I think that...
