Soon, I will be moving into a house and will start using it for my gardens. Personally, I would not use this water for my edibles, but it is "free" nonetheless. I read about this tip from an aquarium forum that I frequent.

Speaking of fish tanks... You can also use pothos ivy cuttings in your aquarium. Fish will not eat this plant and it is so easy to do... Take your cutting and rinse it well as you do not want any plant chemicals in your fish tank. Just drop in the cutting to float and that is it. Betta's love to curl up on these leaves just under the surface of the water line. After sharing this tip, a friend of mine put a pothos leaf in her snake's aquarium. Pretty cool stuff if you ask me! Thank you for letting me share. Until next time be well and have a great weekend!
Always,
Denise

Steve's Aquatic Plant Resource Page is comprehensive and interesting. Here is the link for you to copy and paste:

I hope that you enjoy the links and I hope that the pothos cuttings work out for you. Just try and be patient as they take a long time to root. But even just floating the leaves provides a pretty effect and something interesting for the fish to play with. *smiles* Please keep me posted.
Always,
