Mister Gardener and Altum,

Must be my water - comes out of the tap with nitrAtes between 10 and
20ppm depending on the time of year. Any direct sunlite at all = green
water. Funny though, lights are on a timer and at peak light, I'm
putting 4 watts per gal. in the tank (4 hours). Late afternoon sunlite
would hit the tank if the drapes were open - every once in a great
while one of us will forget and leave them open - by the next morning
we have the start of an algae bloom. Hmmm - mabe it's just that little
bit of extra light that does it (?)

How odd. You wouldn't think that one afternoon of sunlight would make
such a difference. If I were talking to anyone less experienced, I'd
suspect a touch of ammonia in the tank. Nothing like ammonia to get a
green water bloom. I'm sure your tanks are ammonia-free, though.

I noticed that Mr. G and I both have water sprite in our algae free
sunlit tanks. Makes you wonder about allelopathy. Water lettuce has
been demonstrated to inhibit the growth of chlorella (green water) in a
couple of different scientific studies.

I don't have nitrate in my tap water, but I spike nitrates up to about
10ppm after each water change. The water sprite loses its healthy green
color otherwise.

Lots of good information on them there.

Not sure I agree with this page. They seem more interested in telling
the reader about sharp barbs and poisons than about the absolutely
peaceful, gentle, and playful nature of this species. I also disagree
with the feed only at night - Feed right along with your other fish
during the day time, and if they are in a community tank, an algae
disc or a couple of sinking pellets might be a nice "after lights out"
treat.

And please, never put just one or two corys in a tank. They are so
much more active and playful when they have a few other of their kind
around, they don't even have to be the same kind of corys, they school
together and play nice with other corys regardless of size, color,
race, religion, national origin, sexual preference, physical ability,
etc. A single cory in a tank may spend most of its day in a shady
spot, out of the way, waiting for someone to come out and play. This
may lead the fishkeeper to think they are more night active. Believe
me, given some friends, all of my cories are very active all day, and
rest quietly at night.

(I think this is directed at me, after I commented that I don't fully
agree with Wiki Aquarium's entry on a certain corydoras. Please,
people, include enough of the post you are responding to so that we
don't have to guess what you're talking about.)

I have not paid much attention to Wiki and I haven't any interest in
actively participating. I don't feel I have the expertise to
contradict an existing entry on this particular topic, but I also
question the background of the individual that posted it there. I see
this as a potential clash, and I simply don't have the inclination to
get into whatever political dynamics that make Wiki what it is.
Perhaps I'll explore Wiki Aquarium sometime in the future when I have
time to discover a new web frontier.
