This pic is after spending 30 minutes trying to clear this duckweed. Took about 100 lbs of it out of the tank that grew overnight :( I love my frogbit and dwarf water lettuce, but OMG duckweed is HORRENDOUS. I get it lowers nitrates, but fuck I already have three other floating plants, and three massive pothos???? nitrates are NOT my concern lmfaooo.
