I have two aquariums, and I have been using the water (when I do a water change for the aquariums) on my outdoor plants, usually roses. Is this ok for them? Both aquariums are healthy, in that the fish live for years and years, so without an industrial strength chemical test, I'd have to say that the chemicals in the water are balanced (at least for fish).

I use it on my plants and it doesn’t bother them. I don’t think it’s a concern unless you used a lot on vegetables. I’m guessing the duck and goose crap in my yard is worse than fish water.
