Just use that water on your house plants or flowers out in the yard, that's what I do. Saundra >> I have been reading about people using aquarium water on their plants. It sounds like a good idea, but be careful. If you have any of the salmonella or other pathogen-carrying critters in your tank, you could be could be passing that on to your plants. While Mother Nature is pretty good about eliminating said bugs from open air (outdoor)plants, indoor plants may not be so fortunate, and you could end up with contaminated fruit. ...and you think too many Habs make going to the bathroom unpleasant? I'm sure the fishwater is full of all kinds of neat nutrients, but it can be a danger as well.
