When some call it a nuisance does that just mean it can take some maintenance over imte, as in trimming and or removing excess? Wouldn't a fast growing plant like this be ideal for removing nitrates and waste from a tank as they're being turned into excess plant matter in a sense then you're removing them from the tank? Pretty new to plants myself, and may be missing something on the scaping or aesthetic side of this, but it seems like functionally, a nuisance plant is ideal for water quality. Unless it's not as good at pulling nitrogen products out of the waer or something else I'm missing.
I am always puzzled by the use of the word "nuisance" with respect to aquarium plants. People whine and moan endlessly about Duckweed, for example, complaining about the endless and exhausting toil involved in controlling the stuff. Really? Your aquarium has a few square feet of surface area; running a net over it a few times takes a couple of minutes, tops, and easily allows you to remove 95-99% of the stuff, taking with it a crapload of nutrients that have been accumulating in your tank. Now, if you have decided to eliminate it completely, I agree that you are faced with a task...but simply controlling it is child's play. Use the excess as fish food (I add it to homemade gels), compost it, whatever. I let it grow extra dense over my indoor tanks as spring approaches, and then harvest it and drop it into my outdoor stock tanks when I fill them up. Instant filtration!
Same thing with Val. Sure it grows fast and spreads; IMHO, that's great! Thin it out once in a while...doesn't take more than a minute to do it...and use it just like Duckweed. I'm trying to decide if

is serious or not regarding the use of it in salads...but I think I'm gonna try it!
Whether we are talking about fish or plants, it always seems that many people only want things they can't get (Snakeheads, Asian Aros, etc.) or can't successfully keep (fish species that simply won't live in your local tap water, giant monsters, etc.) or that nobody else has (Rare! Endangered! Unavailable!
Gotta have it!!!). Things that are easily available, that are inexpensive and that grow and reproduce readily in captivity get zero respect...but for many us, those types of fish and plants provide exactly the kind of aquarium experience that is most satisfying and rewarding.
