Thank you for the advice. I was considering going for 2x50 and 2x10 watt ones, and setting it up so that i have high light in the middle with darker edges. Now you have me reconsidering to going for maybe 2x30W and 2X10w to achieve this effect. Aesthetically, I prefer light that creates contrast between lit and shaded areas, rather than uniform lighting. I certainly don't want algae problems either. I won't be using CO2
. I am looking to grow moss and ferns and other plants that don't need to be in the ground. I would like these plants to spread densely over the rocks and driftwood. I intend to leave the ground clean, just with white sand, but might reconsider this later.
