Things have drastically improved one month later. I haven't done any water changes (only a couple of top offs) which seems to have been the right move. I also manually cleaned off leaves of all the plants 2-3 times a week and cleaned out the filter floss one a week for a good 3 weeks or so.

The water is very clear now and the precipitate is gone. The duckweed didn't make it. It all melted. If I had to make a guess I'd say that the precipitate chocked out the root system and the plant was unable to get the nutrients it required.

Now that the bloom is gone the hair algae is coming back strongly. I'm in the process of getting my hands on some type of floating plant to boost the competition in the plants favor.

Thanks again to everyone who weighed in with there hunches. I truly appreciate it!
