So the water where I live is on the hard side; not so much that it's unhealthy for fish, but I have a crowntail with some curly fins and I heard that Indian almond leaves might help. Well, those seem a tad expensive to ship, and I read somewhere that oak leaves will work the same way.
I live in Idaho and we don't have a ton of oak trees, but I live on my college campus and I think I found one. Do these look right and do you think it's safe to try? :P
I don't want to do anything that might be harmful /:
Also do the leaves have to be dried out first? ial or any kind
