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.

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?
