Yes it needs to be at the surface of the water, preferably slightly above, so that water falls off the edges. You could make it floating.

Well you'll certainly be overkilling your electric bill!! :lol:Originally Posted by worley
How's this for a light source
Now I just have to figure out how to fit it
That looks really good for a light!
Tell us more. Where'd you get it?

Not cheap at £34, but it's a waterproofed unit, should be reasonably economical to run and the bulbs are available on ebay for not a lot of money
Ohhh I may pop down to my local store, shame I'd need 3-4 of those though.
Installed, sort of, temporarily, well, it can't fall in the water anyway....hopefully :roll:
When I have more space/time I'll use it to build a more professional one.
I thought it would be brighter than this
I had the other little bulb on 24/7 but I understand from these forums that it is better to have on for 16 and off for 8.
Is it better to have a straight 16-8 or would 8-4-8-4 or even 2-1-2-1-2-1-2-1 be better?

The basic idea is sound, as long as you have enough light and flow and it's close enough to the water (I think you still need to get it a bit higher), then it should work.Originally Posted by Rumpy Pumpy
What, the photo or the light itself? Also what colour temp is it? Is it a standard 3500k? The higher colour temps, like the daylight 6500k+ bulbs tend to appear brighter than the same wattage of lower/standard colour temp bulbs, but the lower ones tend to actually grow algae fasterOriginally Posted by Rumpy Pumpy
16-8 is better, I don't think people have tested it in other ways like those combinations, but I'd theorize that the algae prefers more natural cycles/enviroments for optimal growth, hence why they don't grow when the lights are on 24x7
