Duckweed, Boon or Bane I have duckweed in my tank it started from just a couple pieces and now it is almost covering the surface of my tank. I net it out and compost every now and then, but sometimes if i have to stick my arm in the tank it comes out looking like the "Swamp Thing" with duckweed tangled in all the hairs. Is there a benefit to keeping this stuff or should i just try to get rid of it? What sort of tropicals will eat it and get along with tetras? |
