Just wondering about my lighting.

I have a 30 gal with 30lbs of l/s, 10lbs of l/r, just wondering if my 20 watt actnite light is enough to support the stuff living in the rocks and sand.

Rock and sand does not require lighting to support the bacterial colonies, only the corraline algae on the rock, but that is a minimal requirement. You may not get fast growth or really vibrant colors with a 20watt NO bulb, but it will be enough to keep it going.

I have the same tank you do. I bought a double strip light used at the pet store with one white and one blue light for 30$ This will give you 40 watts of light. I get my other 20 watts from a single strip light which is placed right behind the other hood. It has a single white light. This is a lot for me, one day I will get rid of the strip lights and get a powercompact system, but for now this is more than enough. I can grow coraline algae, but it grows slow. You can even get some types of low light corals and place them at the top of the tank. I have a few, but don't get the Xenia they are very fussy and require a lot of light.
