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.
