Use Aquarium Water For Plants

Dirty fish tank water makes great plant food. Instead of pouring all those great nutrients down the drain use it to make your plants look great.


When I clean my 29 gallon tank I empty the water into my kitchen trash container then plunge an empty plastic kitty litter jug into it and fill it with the plant water. An empty cleaned out milk jug could be used.

If you don't use it right away, be sure to shake it before using as it does tend to settle on the bottom. It works better than plant food in my opinion.

Aquarium water is great for plants because of the natural fertilizer in decaying fish poop...however, rarely if ever should an aquarium be 'cleaned', a partial water change allows the beneficial bacteria colonies to thrive, and these colonies convert deadly ammonia and nitrates into less harmful nitrites. Only change 10-15% of water each time, as a general rule. I have been successfully raising and breeding freshwater tropical fish for over 40 years.

We have a turtle in our aquarium. Will that work instead? Someone please let me know. Thank you, jenny

You can print any page on ThriftyFun by clicking on the "Print" button under the title. But watering plants with aquarium water isn't tricky. When I had an aquarium, we would just water all the houseplants and then work our way out to the garden until we had used it all up. The only time it was a concern is if we were treating a medical problem in the tank, which might not be good for the plants.


Good luck and let us know how it turns out.
