Is old freshwater aquarium water good for houseplants?
Deneen asked:
I have an established freshwater aquarium. When I do water changes, I want to be frugal and use the water to water my plants. Is this a good idea?

The old aquarium water has nitrates and some nitrites and is Ph balanced. There is also some diluted salts in it.
