Does anyone use their old tank water to water vegetables in the garden? I throw mine on flowers but wonder if it’s safe to feed veg?
I might be concerned about medications if you used them at all. Just your typical dirty fish water though, shouldn’t be an issue.
I feel like it depends on the chemicals you use in your tanks. A lot of aquarium meds say “known in the state of California to cause cancer” and have warnings to not use on fish you’re consuming. Never read anything about using in garden.
I use it for house plants and they do really well a lot of pond people do it for their gardens but maybe because ponds you don’t put chemicals in them as much since most ponds are self sustaining.
