Houseplants Thrive on Aquarium Leftovers

Swimmy II lives a luxurious life in my living room, in a 10-gallon oasis. He enjoys moving freely and darting around between freshwater aquatic plants and the beautiful rockscape decor I collected on the beach at 91st. Swimmy II is royal, with rich hues of deep blue, maroon, and purple. He seems to sparkle as he glides about. Swimmy is a Betta. He shares his McMansion kindly with The Slippy Brothers. It’s a symbiotic relationship. Three nerite snails slowly chow down on algae and stray bits of tank sludge, keeping Swimmy’s kingdom clean.

It’s a big job for The Brothers, but free food and rent make for a sweet deal. The plants produce organic matter, and along with remnants of Swimmy’s bloodworm feasts, debris accumulates in the tank. The Brothers do a great job, yet every month, Swimmy relies on me to change his life water. Even with a bubble maker and his snail servants, his water needs refreshing, to maintain oxygen levels and to ensure healthy water quality.

Now here’s the hack: when caring for your fish by changing a freshwater tank, consider using the spent aquarium water to water your houseplants instead of pouring it down the drain. This saves by recycling it, and it saves on plant fertilizers. Aquarium water is a rich source of nitrogen, which is what plants need to make chlorophyll, an essential component of photosynthesis. It also contains phosphorus, which supports healthy root growth, and potassium, which makes plants strong and helps them hold water. Used fish tank water also contains beneficial bacteria that break down ammonia and help feed the soil.

I use an aquarium siphon vacuum cleaner to gently suck up debris and water from the rocks. It’s simple to use and lets you target the gunk that settles at the bottom—uneaten food, plant matter, and other nutrient-rich sediment. If you don’t have a siphon, just take a wooden skewer and gently stir the gravel around. This loosens up the buildup so it can be captured when you scoop out the water. Either way, the goal is to collect the “good stuff.” Then simply use that to water your plants.

I love the idea of one living world, sustaining another, and this is exactly that.

For a healthy look, rotate your houseplants slightly every two weeks for even light distribution which encourages symmetrical growth.

I know many of us are focused on our outdoor garden now, but take notice. As indoor plants wake from their winter dormancy, the increasing hours of sunlight trigger a surge in growth. In addition to regular watering and fertilizing, be sure to prune your houseplants to encourage healthy new growth. Rotate the plants slightly every two weeks for even light distribution, which encourages symmetrical growth. I also give my plants a shower—literally, in the shower. This washes away dust that has collected on the leaves, allowing for better absorption of sunlight, and it rinses off potential pests like spider mites.
