flocculents and fish
News from the "green water front":
The battle continues. I have the green water in my
40g tank under minimal control. That means that after
I change water or diatom filter the tank, it looks clear
for one to two days. By the end of the second day, it
looks a little cloudy; diatom filtration at that point
results in light green diatom powder after 1-2 hours.
I have also, several times (but never more than twice
a week), tried flocculents. At first, I used Kent's Pro
Clear, but switched to Crystal Clear (Aquarium

although the literature (Baensch) says they don't like
high nitrate; it says nothing about flocculents.
Do you more fish-oriented types know why these
flocculents seem to have this bad effect? Are the
flocculated particles clogging their gills? I have quit
using the Crystal Clear in favor of just diatom filtering,
but I don't think it works as well this way to get rid of
