Has Anyone Else Used Guava Leaves?

[DerpPH]

Hello everybody ok so I decided to get some guava leaves for my amazon biotope(got them from the garden and no we don't use ferts or pesticides) and I was wondering, does anybody else use them? Im gonna make a bronze corydoras biotope along with glowlight tetras. I have read a few good reviews online but I want to hear from you guys
