I gots a few plants today at my lfs and I asked for a few duckweed, I never
saw it before and was surprised that it was
so small. So he gave me like 5 pieces for free. I've read posts that in a
few days this will overtake the surface? Will this happen to my tank given
such a small starting amount?
thanks

It might, if nothing eats it. It doesn't grow rapidly in my tanks,
not sure why, but I don't particularly want it, so that's okay.

I have discus cardinal tetra and otos. I dont think they will eat it? I am
trying it
in hopes to get rid of an algae problem.

The duckweed should be safe from those. Are you growing other plants
in the tank? If not, why not just cut back on the light? either less
wattage or fewer hours.

If conditions are right, you better believe it! I got mine that way, and
now I have to throw net fulls of it away every 3 or 4 days. I like growing
plants, but this stuff is quickly becoming a pest. It will rob the light
from your bottom plants, and it can cause a major PH crash and suffocate
your fish if you inject CO2 and you don't stay on top of this stuff good
enough and let it take over the surface. I learned this the hard way too.

Duckweed isn't a plant, it's an infection.

Maybe I can bring one of the goldfish in for a few days to clean up the
big tank. Stupid duckweed.

It multiplies rapidly in warm water with good light but doesn't compete well
with other plants. Some fish will eat this plant. Goldfish devour it!

I have discovered that adult pink convicts eat the hell out of it too. If

I cant seem to get rid of this hair algae problem. I tried less light but it
still seems to hang on.
I recently added some more plants to consume more of the available nutirents
( left over food etc). I've read in this group that DW is great at getting
rid of algae. This algae problem all started when I took out this lilly pad
type plant. It must have been keeping the algae problem down. I wish I knew
what the name of it was, I'd buy another.
If the duckweek gets to be to bothersome, why cant I just net it all out?

Netting it out should work if you can get all of it. My tanks always
have plants with leaves on the surface, so without taking everything
out of the tank a little of the duckweed remains. Then it multiplies.

Taking some out from time to time will be essential if you want to
reduce the nutrient load, just letting the plants grow and die does
nothing. I also have hair algae, it is getting less and less as the
tanks age, mine were all recently set up again. I just grab it by the
handful and pull it out.

Hi..

[lemna]

Have ever had it in tanks and summer ponds.

Need > 8-12 milligram/l Nitrate or will otherwise stagnate.

If it were growing significantly I would "harvest" it by the
week. In my mind it's a useful plant filter.

Make your decision: Love or hate it! :-)

How does it propegate? would it be a good plant filter for a sump style
filter? Or would it be hard to keep out of the main tank? I would think
simple mechanical filtration would be able to keep it in place.

Unrelated question... does anyone ever light their tanks from the side?
Does the glass make a significant effect on the amount of light that
passes through? I ask because I have an all plant aquarium for growing
out plants on a shelf that hardly has enough room for the hood. It
would be so much easier to put the light fixture behind the tank for
easy access to the surface.

Not if you have a lot of tanks. I've almost got rid of it, andhave been trying
for about a year. One lousy piece is all it takes. I've throw away pounds of
that crap.

The plants grow weird. Why not a lot of LEDs?

I grew an amazon swordplant to much greater size by lighting through the
glass side of the tank it was in and it grew allot in a short amount of
time. I had the light closer to the plant this way because normally the
light has to be at least a foot above the water surface so the popping
bubbles don't get onto the bulb too much because if it does the fluorescent
screw in bulb will die. But I stopped keeping the light coming in from the
side after a certain point because some hair algae started growing on the
glass that had the light real close to it. Good luck and later!

You must be losing a lot of light if you are keeping it a foot above
the water. Why not add a glass cover and set the light housing
directly on the glass, elevate slightly only if the bulb touches the
glass. The glass will also slow down evaporation, conserve heat, and
(better double check with the plant experts) reduce the rate at which
your water is losing CO2.

I'm clueless as to using them in a sump since I have freshwater fish only.
They should do well anywhere there's enough light and nutrients.

All the plants would look horrible because they'd all be leaning towards the
lights.

====================
I use the screw-in fluorescent bulbs in my tanks (except the 55s) and the
only one that died was the one I dropped in the water. Well, I dropped the
hood it was screwed into in the water. Bummer,... the bulb was only a few
weeks old.

=================================
That may be true with a lot of tanks but I just skim it off the surface with
a net and feed it to the koi and goldfish. They consider it the best salad
they ever had. :-) If you want to get rid of it for good keep one
goldfish around and move it from tank to tank.

If the conditions are right, you better believe it! I have my way, Now I have to give up its net filling every 3 or 4 days. I like to grow up Plants, but they are quickly becoming a pest. This will be robbed of light from the bottom of the plants and can cause major accidents PH value and suffocation Your fish, if you inject carbon dioxide and you do not stay on top of that good stuff Enough, let it take over the surface. I know it too hard.
