assistant: Here's the windup...and the pitch...
  Wowsers!  I finally got a toss that beat the tide!  :)  Thanx!
  Not having to replace airstones and fix or replace air pumps would sure be
nice.  Besides, the old saying goes, you can never have too much filtration.
  Yup.  I'm afraid I get a bit lax in that, working as much as I do right
ow.
I still replace 1-3 gal of water every week (my plants *love* the stuff!) in
addition to replacing the water that has evaporated (many 90 to 100+ days
lately.  Did somebody mention global warming...?)  I supose I should be
replacing a lot more in a 20 gallon tank...at least 30% a week while the UG
is the only filter running.
  Really?  That's a new one on me.  Gotta start keeping up on the water
changes.  The building management is going to wonder what has gotten in to
ll
their potted trees... }:)
  I'm trying a light-limited/algicide regimin to see if I can get rid of the
stuff entirely without killing the other plants and stressing the fish too
much.  They get some indirect sunlight (not much, the tank is behind some
shelves on a wall away from the windows) during the day and a few hours of
artificial light when I get home at night.  So far, so good.  The acid test
will be to let the tank gor for a few weeks with more light to see if the
stuff returns.  We will see.
  Many thanks, oh far away one.  :)  My new apartment is much smaller than my
old one so it's going to be a real challenge to set up all my tanks.  Hmmm, I
wonder how the fridge would look with an aquarium on it...?
