It's really hard to tell from a posted image, but I will say that it looks ok. Red light can often seem a bit more dim than it actually is.

I'd say try it the way it is, and see how you make out. You'll likely be just fine. If not you can always add more light. This is a case where you want to use just enough light to do the job. You don't want to over do it, and consume more power for no additional results.

Hello Clown fish and Fellow Floridian ! Santa Monica can give You good advice . He helped me out a "lot"

We find that most people need about 24W of high quality red LED light and about 3W of either 420nm violet or 440nm royal blue, for each side of the screen. We aware that a high quality 3 watt LED such as a Luxeon can output almost twice the power of chinese 3 watt LED. Same to be said for the 9W LED, slim chance it is outputting anywhere near enough light for optimal scrubbing.
Algae can handle a lot of light!

Hope that helps?

Just remember that with submersible lights, they add approximately 25-50% of the total wattage output in heat to the water. For example, a 20W submersible LED light can add up to 10W of heat to the water.


I think you were on the right track going with external lights.

(Edit: Sorry Santa Monica, I didn't see that you were a sponsor! I hope my comment didn't come across as rude. Just making him aware of some facts without promoting any specific light brand of product.)
