    For the water quality of the fish tank, filtration is an indispensable part, and filtration is divided into physical filtration, biochemical filtration, and plant filtration. The most common of these filtration systems is the previous physical filtration and biochemical filtration. Although plant filtration is also used by aquarists, it is rare.

    Plant filtration is to let the water in the tank or pot pass through the roots of green plants, so that it can absorb harmful substances such as organic fertilizer (fish stool) and nitrate in the water to achieve the purpose of purifying the water quality, even if the water quality is purified. Nutrient growth is the beauty of both!

    Benefits of fish tank plant filtration system:

    1. The roots of plants in plant filtration can absorb many harmful substances, nitrate.

    2. Plants can also release more fresh oxygen through photosynthesis.

    3. The presence of green plants at home adds to the beauty of the environment. We can also refresh our environment. Since there are so many benefits, why not increase plant filtration?

    Plant filtration requires 3 conditions: Sufficient sunlight to produce photosynthesis; Sufficient fertilizer for its growth; and Green plants suitable for hydroponics. Plant filtration requires a large number of plants to achieve. If only one pot or two pots are not good, but they can also achieve the effect of being green, but I think fish friends will not rely on two pots to raise fish.

    The plants suitable for planting in the fish tank plant filtration system are:

    1. Scindapsus Aureus
    2. Araceae plants
    3. Commelinaceae

    When planting these plants, it should be noted that the roots of the plants cannot be completely immersed in the water. The 5-6 cm roots are best exposed in the air, so that even if the roots soaked in the water cannot absorb enough oxygen, they can still Let the exposed roots add oxygen. There is also the need to change water frequently.
