I am curious to see if anyone has tried this. I couldn't get my nitrates below 20 ppm and i got the idea from high tech refugiums to try something a little different and low tech. So i cut probably 6 vines from a pothis and stuck them in my fish tank. Within days they were sprouting roots and now they all have long roots growing out of control, but the important part is it has brought my nitrates down below 10 ppm. I knew it was important for my rays. Has anyone else had any luck with this?
