Here are pictures of my setup, its a single pump system. Uses four 23w CFL bulbs and I commonly harvest 1 cup of algae.
This was my harvest from a few weeks back. This Sunday I will post my current harvest results.
This is a full tank shot for reference, its 6 months old and never has had any algae issues.
Here are my last testing results.
