I have about 6 on my 75. They're useless for denitrification (unless you use something like 50). They're more of a novelty to me. I don't know what I'm doing wrong but they are the slowest growing things ever, and it's not a lighting issue and it's not a misting issue. I bought them in 2002 as pods and now almost a full 4 years later they have maybe about 6 leaves each or so and about 12" tall.
I should mention that although I find them useless for denitrification, that's a little like saying fish are useless for denitrification. I don't mind having them but I don't have them to serve a specific purpose other than "they're coooooool."
