I've got some in my ac110. You should have seen how many roots were growing in the old filter sponge in there when I cleaned it last week haha. They have been in there for maybe 2 months and I think they have acclimated fully. The pothos was 3 bucks for a small pot and I got a clipping from my bf's mom. I'm also trying an experiment with mint and green onions and it seems to work. My mint was in the crappy soil from the back and it has started dying so I put a stem in, it came back good.
I was contemplating doing this with some of my basil but aren't you worried about the plant leaching chemicals into the tank? How do you know if it's safe or not?
