Banana Peels Can Purify Polluted Drinking Water, Scientists Say
I came across this article about how banana peels can be used to filter as a filter medium. I found a couple of points quite interested. Banana peels can be reused up to 11 times for filtering compared to active carbon. Banana peels contain nitrogen, sulfur, and carboxylic acids. Hmm..those are some things that our plants could use. I'd be interested to see how well they help in our aquariums.
