It turns out that my source for Daphnia didn't work out. Since there would have been some other small critters in the culture that I couldn't confirm were shrimp safe, I didn't want to risk it. I was looking into get some Daphnia from another source, but then I noticed that the GW seemed to be clearing just a little. The last couple of weeks when it's been time for a water change I was actually still able to see about an inch into the tank. The prior couple of weeks the water change would get me about an inch of visibility into the tank which would drop to zero by the next water change.
After today's water change I was actually able to see almost to the back of the tank!! I'd say that getting my CO2 back in line and letting the plants do their thing was enough to knock it back. I'm hopeful that in a few more weeks it will be completely gone.
This will be the second time that I have beaten Green Water without a blackout or other extreme intervention. I've come to the conclusion that while these may help to remove GW more quickly they aren't ultimately necessary. Basically you just need to get your CO2 and nutrients in line, and then have some patients.
