I would forget about the first 3 on a 12 inch screen. IMO the light spread would be too narrow. You probably would end up with green hair algae in the middle section but slimey stuff around the perimeter. That is my personal experience.

If using any of those lights, I would set up 4 of the http://www.ebay.com/itm/ABI-12W-Deep...3D122173168864 on each side. This I believe would give you about the correct wattage, & also an excellent & even spread of light.

Also, IME, i have found that 660nm reds are all the color needed to grow emerald green hair algae. I don't bother with any blue.


Santamonica & Turbo may disagree?

good luck.
