Silly question

I know it's a silly question, but can I use bananas as a source of potassium? As in dosing bananas in my tank

I'm no chemist but I wouldn't think that the potassium source in a banana would be readily available to the plants. I mean the banana would probably have to start to break down in someway in order to release its potassium. Which in turn could be inviting a large array of problems into your tank with decompossing fruit as a fertilizer source. However you could possibly mulch bananas into a soil mixture and use it in a dirted tank afterwards.

Bananas aren't all that high in potassium, really, so even if you wanted to compost your own high-nutrient ferts they'd probably not be the best (or most economical) choice.

My understanding is that plants cannot take in iron from rust. Other organisms need to work on it, or other processes until it is in a form that plants can use.

So, yes, ultimately the iron could become available to the plants.
Is it worth waiting around that long? No.

A lot of dutch style people used to do this to my understanding. You bury the nails in the substrate to provide iron to the roots.

Perhaps potatoes would be a better option! :P Dig too far into this though, and I think you'll find potassium vitamin supplements about the same price or pricier than aquarium supplement. Maybe check out your local garden store if you are looking for cheaper options?
