How Aquarium Water Can Benefit
Your Garden
By RHIANNON FAITH IRELAND
The aquarium water you usually throw down the sink contains microorganisms and minerals, like phosphorus, ammonia, potassium, and nitrogen, that help plants bloom and grow.
If you're worried the water is too potent, dilute it with equal amounts of clean water. Then, use a watering can to water your outdoor or indoor plants to encourage faster growth.
However, avoid watering plants with this water if you have a saltwater fish tank, use chemicals or other medicines in the tank, or your plants have already started to flower.
