Tagging along. I am picking up a used 29g with wrought iron stand tomorrow night. Consider suspending your light from the ceiling, Catalina fixtures are super light. I have a 3 bulb over my 75g Rip suspended with simple a simple black chain. This way you can move the light up some if your having algae issues.
I have a Fluval 305 available, so that's what I plan on using for a filter. Your scape looks great, what type of rocks are those?
