Very nice! Make sure the whole screen on both sides is covered and getting enough flow. Once it starts getting seeded with hair algae, you can turn up the flow.
I didn't even have a diatom bloom in my 20g as I was running the scrubber - the scrubber turned really brown though! Then it started turning green. I got pics posted somewhere...
I'm excited for yah! Can't wait to see your results in the next two weeks. Oh yeah, that's how long it takes to get a screen started. lol
