BGA or worse???
 

Is this BGA or something else?

The stuff is very dark little globs which "hang" (up) on the plants - +boyancy.
Slimy, very smelly. Globs appear black, but are really dark green. Stuff
"pearls". Stuff will float off if plants are brushed. The water gets cloudy. A
prefilter (just floss) on the filter intake will turn a blue green, and
eventually to deep blue toward black. It gravitates to the above gravel line
"roots" (whatever you call the nutrient collecting tendrils that grow above the
gravel line) and fine leaved plants like firl or water sprite. Tends to mostly
show up on the edge of broader leaves. In the evening this will cause the
appearance that the plant is pearling, but I think its the ??? algae/bacteria
that's "pearling".

I tried maracyn, but at the 1/2 dosage recommended on the rec.aquaria notes on
BGA. It did diminish during treatment (but I was running a diatom filter at
the same time) but has now returned. If this is just BGA, do I now go back to
maracyn but at the full "sick fish" dosage? (when I can get some more
maracyn).

Many thanks in advance,
Sharon

Sounds like BGA, all right.

I had this problem before I got a Python, whenever I let the tank go too long
between water changes. I also sometimes get it when the tank gets too
overgrown, and there's not enough circulation. (Usually growing at the top of
the tank, even floating on the water.) Cutting the plants back so they don't
touch the surface of the water fixes that.
