The whole neighborhood uses it for their flowers, and after a month of neglect it still runs wild all over the balcony

Can fish tank water be used to water flowers?

Keeping fish means changing the fish tank water often. Pouring it straight down the drain is really wasteful, so using it to water flowers is the way to go!

1. Adjust soil acidity and alkalinity

Water from a fish tank is slightly acidic, with a pH mostly around 6, which benefits plants that like slightly acidic soil, such as pothos, copper coin grass, Monstera deliciosa, peace lily, spider plant, narcissus, and hyacinth.

2. Provide nutrients and fertilizer

The water in a fish tank contains nitrates, nitrites, ammonia nitrogen, fish excrement, and other substances, which can provide the nutrients plants need for growth.

What should you pay attention to when watering flowers with fish tank water?

1. Let it sit for a while before watering flowers

In summer, the water in a fish tank and the soil in a pot have a certain temperature difference. It is best to let the fish tank water sit for one or two days until it returns to room temperature before using it to water flowers, so as not to affect plant growth.

2. Control fertilizer

Fish-keeping water contains a certain amount of nutrients. For plants in a period of vigorous growth, you must reduce fertilizing to avoid leggy growth.

3. This kind of fish-keeping water cannot be used

If disinfecting salt or other fish medicines have been added to the fish tank water, do not use it to water flowers, otherwise it will cause the plants to dehydrate and dry out.

How do you grow flowers and keep fish at the same time?

1. Container choice

It is best to choose a hydroponic bottle with a planting basket. The space should be a bit larger, and when adding water the water level should be a bit higher, leaving enough room for the fish to move around.

Of course, if conditions allow, you can buy a larger fish tank equipped with a water circulation pump. With more space, you can also keep tropical fish and aquatic plants, giving it higher ornamental value.

2. Choosing fish

Growing flowers is the main purpose and keeping fish is secondary. Because space is limited and oxygen and other nutrients in the water are also limited, you must choose small fish, and the number cannot be too many. 1-3 is enough, otherwise they will not survive easily.

3. Choosing plants

First, hydroponic plants must be non-toxic. Toxic flowers like dumb cane are not suitable for hydroponics with fish. If the sap on the leaves drips into the water, it will not only damage the roots but also poison the small fish; plants that prefer alkaline conditions are also unsuitable.

4. Treating the water

Tap water at home must be left in the sun for one or two days before use. The chlorine in the water is bad for both the fish and the plant roots and can easily cause death. In summer, you must change the water frequently to keep the water clean.

5. Stop feeding fish food

The rotten roots, old roots, and residual roots of the hydroponic plants themselves, as well as the microorganisms originally in the water, are enough for small fish to sustain life. There is no need to feed them fish food, otherwise it will easily pollute the water quality.

Flower lovers, keeping fish has many benefits,
