Aquarium wastewater makes fantastic, nitrogen-rich plant food.
If you have an aquarium, consider the value of the wastewater you siphon off every time you clean it. One of the best things you can do with this nutrient-rich fish water is to offer it to your plants, both indoors and out. Organic, nitrogen-rich aquarium wastewater can give your plants a nutritious boost any time of the year. Plus, it’s already diluted, so you won’t have to worry about it burning your plants.
