Algae turf scrubber--- wave length of light

[Ian]

Ok guru's
I am planning a turg scrubber for my new fish room. What wavelength of light would be best?
I want to use LED's to light it and the tank I am planning on using for this build will be more than large enough.

Yes--- I will start a build thread once things are a little more planned out... right now the fish room is bare 2*4's and drywall only on the exterior of the room.... For some reason the wife thinks bathroom's and bedrooms are more important than fish room's

Check out reefsupplycanada.com and see the fuge led lite that they just started selling

i use a combination of red and white 1 watt leds-grows the algae really well

thanks..I have a cheap LED here that I will try on one side....it grew algae great in the tank and I will try one of the ones from reefsupply canada on the other side. This scrubber will be large enough that 1 side has enough square inches to take care of my tank. Man the itch to get a tank back up and running is killing me

Just looked at that light, looks like a great deal!

What kind of coverage do you get from it?

[nrosdal]

I just have it temporarily hung at about 7" above fuge and it covers the 17"x14" i would imagine a 20-24"x16-18" at a higher mount height.

I had 8 CREE red's on mine, 4 on each side of a 2 x 10 inch mesh

did not grow a thing, 5 months long waiting, and waiting.


when I build the unit, I put the LED's right at the screen, about 1 inch off.

I have bin informed that this was way to close, 4 to 6 inches would have bin better,

my problem is, is that I build it all to be 1 inch, and thus removed it after 5 months, as I have to rebuild, so I can have more space between the mesh and led's

I don't know if there is a real wrong color, as some use regular bulbs, some T5 or CF,

I think it is a bit playing around, or gust check what LED's are used on manuf. units.
