That's not a bad place for it. Anytime.
Oh- don't forget that fish tank water also has relatively high sodium levels compared to what your plants like. That's why successful aquaponics systems require a special low-salt fish food. FYI.
stinkyattic Reviewed by stinkyattic on . Aquarium water Has anyone ever tried to use there old aquarium water to water there plants? I know some fertilizers use fish emulsions, so wouldn't this essentially be the same thing? Just me thinking out loud I guess. Really don't know if it would actually be beneficial. Rating: 5
