Clean plants of duckweed?
So, I used to have Duckweed. Due to moving, I managed to utilize the sterilization method --- kill everything.
Right now, I'm starting a tank with some plants, but to get them, I'm worried about introducing pests.
Plenty of literature on snail elimination.
However, duckweed search comes up with a lot of information but none that answers my question.
What's the best way to clean new aquarium plants to make sure you won't have duckweed?
Even if they seller says they don't have duckweed, I'm not trusting it, so I want to take precautions. In fact, I bought some moss from a seller off CL that claims she had no snails or duckweed and what did I find when I got home, one tiny piece of duckweed and a few snails. <sigh>
My plan is to rinse the plant thoroughly, then put it in a QT tank. Let the lights run and see if anything grows (ie. duckweed or snails or other pests).
However, if duckweed does appear, are there any more proactive measures to make sure they're eliminated? My plan was to clean plant again, drain and sterilize equipment, and try again... and again... and again... etc until no duckweed occurs.
Yes, I'm determined not to have duckweed.
