*Week 8 Update*
Here is my growth after nearly 21 days of not cleaning. I had a decent amount, but still not pleased with the overall growth. I'm going to let the scrubber run until the end of May. If I don't see results I will either bump the light as suggested by Santamonica, or build a waterfall scrubber and use the current 2 LED's and mount them closer to the screen. I did a screen cleaning and will update again next weekend.
Nitrates are still stable at 100-160 ppm.
Thanks for the help everyone!
