Can Pothos Grown in Water Be Kept with Fish, and Detailed Explanation of Water Change Frequency
Pothos (Epipremnum aureum) is something many people absolutely love, and its growing methods are also loved by a great many people. Pothos can be grown hydroponically. Can pothos grown in water be kept with fish? How often should the water be changed for hydroponic pothos:

Can pothos grown in water be kept with fish:
The answer is yes. Because pothos is itself a water-grown plant, it comes to life as soon as it meets water. And putting fish, especially goldfish, into the container of hydroponic pothos creates a lovely contrast with the green leaves of the pothos, and the key point is that it has no adverse effect on either the fish or the pothos. However, you must pay attention to whether the pothos has rotten leaves or similar issues, because if rotten leaves or rotten roots are not cleaned up, they will affect the water quality and thereby affect the fish.
How often should the water be changed for hydroponic pothos:
In fact, water-grown pothos should not have its water changed often. Normally growing pothos only needs its water changed once a month. Of course, if the water quality becomes dirty, you can change the water promptly to keep the pothos roots from turning black.
If the pothos has just been grown in water and new roots have not yet grown out, you can change the water more frequently during this period, changing it once every 3-4 days. After the pothos grows new roots, you can add nutrient solution to it, as this is the only way to make the pothos leaves more glossy.
When changing the water for pothos, you might as well rinse its roots first before putting them back into the water. Because pothos has very high requirements for water quality, the replacement water is best tap water or well water that has been left to stand for a few days. Clean water quality is the prerequisite for ensuring that pothos grows tender white roots.
Hydroponic pothos can be kept with fish, and this hydroponic pothos does not need frequent water changes; generally it is once a month.
Does hydroponic pothos need nutrient solution? How to grow hydroponic pothos
Hydroponic pothos is grown directly in water and has no soil. Many people know that plants need to survive by absorbing nutrients from the soil, but hydroponic pothos has no soil, so many people worry that it cannot be kept alive and therefore want to rely on nutrient solution. So, does hydroponic pothos need nutrient solution?
It is completely fine, so rest assured, and pay attention to the following points: put more stones in the water, preferably maifan stone, to provide the nutrients the plant needs and also absorb dirt. Absolutely do not add nutrient solution, as it will not only breed bacteria and affect the survival of the fish, but the inorganic salts will also be unbalanced and the fish may not be able to survive at all. Change the water frequently; there is no need to say more about this, as there is a lot of excrement. Pay attention to the type of fish; do not choose the overly delicate kind. Toxic plants such as tiger taro cannot be kept with fish.
For water-cutting propagation, that is, cut off stem nodes that have aerial roots and insert them into water. After the aerial roots adapt to the water environment, they will begin to sprout and grow, but the water quality must be kept clean. After being planted in water, it is not very adapted to the hydroponic environment, and its recovery and growth are slow; it may even develop root rot after being planted in water. In the initial stage of entering the hydroponic environment, the water should be changed frequently, preferably once a week. After growth becomes normal, it can be changed about once every 20 days or 30 days. Only after new roots have sprouted and normal growth has resumed can the frequency of water changes be gradually reduced.
Hydroponic pothos likes warm, humid environments and requires loose, fertile soil with good drainage. Hydroponic pothos is extremely shade-tolerant and can be placed indoors in a sunny spot all year round. In indoor areas with dim light, it should be moved every half month to a brighter environment to recover for a period of time; otherwise, the internodes tend to elongate and the leaves become smaller.
Does hydroponic pothos need nutrient solution? If you want hydroponic pothos to grow better, then you can give it an appropriate amount of nutrient solution so that it can grow better in water. But with ordinary patient care, hydroponic pothos can also do without nutrient solution.
How to grow hydroponic pothos so it grows fast?
Compared with soil cultivation, hydroponic pothos grows relatively slowly. No matter how well it is cared for, it is not as good as soil-cultivated pothos. However, hydroponic pothos is simple to care for, and for lazy people it is the simplest method. So how can hydroponic pothos be made to grow faster than expected?
The water volume must not be too much
Water-grown pothos must not have all its roots submerged in water; 1/3 of the roots must be exposed outside, and the leaves must not touch the water, lest they rot and affect the water quality. Do not change the water too often; once every half month is enough, and in the meantime just add water when the water level is low.
In addition, hydroponic pothos should be given a wide-mouthed container so that the branches and leaves have enough space to grow, and the water surface has enough contact with the air so that oxygen is more plentiful.
Root trimming + sunbathing
Every time you change the water, promptly cut off the softened old roots (many flower lovers overlook this), which can save part of the nutrients. In addition, place the pothos in a place where it can get sun, let it see more sunlight, and ensure air circulation.
Stop keeping fish
Keeping fish in the container of hydroponic pothos is firstly for aesthetics, and secondly because the organic matter produced by the goldfish can provide nutrients to the pothos and can also prevent green moss in the water. However, goldfish consume oxygen in the water, and the pothos grows slowly because of the insufficient oxygen.
So if you want hydroponic pothos to grow fast, it is better to take the fish out.
Use nutrient solution
Adding nutrient solution is a way to promote the growth of pothos, but it is not suitable for long-term use. Each time you change the water, add 2-3 drops to the water. When adding nutrient solution, green algae may appear in the hydroponic container, so when changing the water, clean the container thoroughly. (Nutrient solution is the last choice.)
Bingo, this article is the advanced version of pothos cultivation. If you are a beginner at growing flowers, you still need to learn to crawl first, and then run. Buy a pot of pothos and bring it home, and first understand the basic situation of pothos, as well as the cultivation methods and precautions for pothos. As long as you truly put in the effort, pothos will not disappoint you.
