actually it is more question than answer..

1. if we add k-leaves just for its medicinal properties and add water clearing chemicals, like purigen, will the medicinal effects be removed?

2. i was intending to add k-leaves into my planted community tank with

18 neon tetras
8 zebra danios
2 bronze corys
3 panda corys

would the fish/plants be affected?

hence my objective would be to get clear water with the medicinal properties of k leaves and happy healthy fish.
