The filter went with the fish to the hospital tank,
where they were treated for ich. I had planned on
adding more fish, but I put that off until the ich
problem was solved.
The 'fuzz' is apparently a cyanophyte, aka BGA. I
confirmed this by viewing a blob through my 8-year
old's science lab microscope.
I have some circulation problems in the tank. The
most affected area is a well lit spot with poor water
flow. The cyanophyte has begun to creep across the
front of the glass and almost every plant has _some_
on it. I have a plan for correcting flow, and I
should have it fixed (hopefully) tonight.
Tomorrow night, I start the H2O2 treatment. I plan to
use 1/2 oz of 3% H2O2 (for 10 gallons), and dose every
I had also planned on fertilizing the plants using
clay balls and 15-0-15 fertilizer. Now, that's on
hold too. Does anything EVER go as planned with a
planted tank? ;)
