Re: Greenwater and lighting
Scott writes and makes a number of excellent points. I respond to a few.
<< I run the lights in my fishroom on timers set to gradually go on one after
another. "Sunset" also is a gradual process.>>
You are truly committed to the welfare of your fish and plants! My
come on and go off all at once. But all the tanks get some indirect
it's not too great a shock.
I don't think daphnia care as much as fish do, but they too get some
<< By the way, livebearer guru James Langhammer, in a much alluded to posting
on his Russian daphnia, recommends leaving at least a small light (kind of a
moon?) on 24/7 over the daphnia so they will not gather in a corner of the
raising container and suffocate.>>
Before the lights go on my daphnia seem to be well scattered, but
maybe pulex are different from moina.
<< Especially if you are using your light to grow greenwater in with your
you want you light as close to the tank's surface as is possible, safe and
I have never been able to produce green water consistantly for a long
so I use the soy flour and yeast food, which works quite well, although
green water would give a greater yield.
<<. . . snip . . By the way, on the killie list they have had several
threads recently alluding to lighting. One which especially got my attention
was the consideration of how reflective the light cover/ hood is. That can
make a huge difference in what really gets to the tank. Someone kidded about
using the aluminum foil from potato chip packages (like I need another excuse
to eat potato chips). Wright Huntley, who sometimes also holds forth on this
Digest too, startled some readers by noting that the reflectivity of those
foils might indeed be useful that way.>>
There was a recent posting to The Angelfish Forum by a woman whose
angelfish were showing significant distress, collecting in a corner and not
moving even for food. She received a lot of replies about possible chemical
or disease problems. Finally one person suggested that perhaps the aluminum
foil she had recently added to her reflector could be causing distortions and
confusing the fish.
The foil was removed, and the fish immediately began to act normally.
<< Raising daphnia, what with the feedings and water changes which will
increase your culture's productivity, (actually 2 or more cultures is
better...) begins to sound a lot like raising fish.>>
LOL! Actually, sometimes I think that I get a bigger kick about
than the fish. At the present time I have white worms, daphnia, micro
Grindal worms, and microworms. And the mosquito larvae have just
the backyard tubs, too which some of the indoor daphnia will soon be
Good luck to all!
