Since these two plants have decided they cannot coexist I was wondering if anyone can weigh in on which one they think is better and why? Which is better at ammonia uptake and removing other impurities? Which is easier to maintain in a planted aquarium? Which looks better? Which a better oxygenator?

Does anyone have any other favourite floating plants?

That make total sense re: floating plants not being water oxygenators. They are "air" photosynthesizers - I'm sure there's a scientific term I'm missing out on here. haha!

So what you're saying is 30 grams of duckweed will do the same job as 30 grams of water lettuce. The only difference is 30 grams of duckweed might cover 50% of my tank surface area, and 30 grams of water lettuce may only be one plant. Do I have that right?

Is water lettuce generally as prolific as duckweed?

Or is it that which ever one grows fastest and proliferates more will do a better job? More plant growth = more detoxification?
