What plants are suitable for hydroponics in an aquarium
In creating an ecological aquatic-terrestrial landscape indoors, hydroponic plants for aquariums have become a new favorite in modern households. This method of coexistence between aquatic plants and ornamental fish not only purifies the water quality but also creates a natural aesthetic effect that combines movement and stillness. By selecting the right plant species and mastering care techniques, it is easy to achieve an ecological balance of dual purposes in one tank.
Selected recommendations for hydroponic plants in aquariums
Application of富贵竹 (Fukien bamboo) in hydroponics
As a classic hydroponic plant, the erect stems of Fukien bamboo create a vertical spatial beauty with the swimming fish. Its well-developed aerial roots effectively absorb ammonia nitrogen from the water. It is recommended to plant 3-5 stems in each tank to form a community effect.
Shaping underwater landscapes with 绿萝 (Epipremnum aureum)
The trailers of Epipremnum aureum can create an underwater forest landscape, with the leaves growing 2-3 cm per week, which requires regular pruning. Be sure to keep 5-7 functional leaves to maintain photosynthetic efficiency.
Creating floating landscapes with 铜钱草 (Pennywort)
The round leaves provide shading on the water surface, which can inhibit the excessive growth of algae. It is recommended to pair it with sunken wood to fix the roots and maintain a 30% water surface light transmission rate.
Building an aquatic-terrestrial symbiotic system
Ecological proportioning plan
Follow the principle of 0.5 medium or small-sized plants per liter of water, and it is suggested to pair an 40cm aquarium with 8-10 hydroponic plants. Small fish species like孔雀鱼 (Peacock goby) and 灯科鱼 (Lightfish) are the first choice, avoiding root-eating species.
Water quality circulation management
Adopt the two-thirds water change method to retain the existing nitrifying bacteria. Test the pH value weekly to maintain it between 6.8-7.2, and control the TDS value within 150-200ppm for best results.
Lighting control system
Ensure 6-8 hours of scattered light exposure daily, and maintain a 30cm distance when using full-spectrum LED lights. It is recommended to set a 1-hour gradual lighting mode for both morning and evening.
Key points for long-term maintenance
Maintenance of root health
Gently wipe the root slime with a soft brush every 3 days, retaining the beneficial bacterial film. Trim brown rootlets immediately and apply activated carbon powder to the cut ends to prevent decay.
Nutritional supplement plan
Add 2ml of hydroponic nutrient solution monthly, combined with natural nutrients from the decomposition of fish food residue. Avoid using fertilizers containing copper elements to prevent fish poisoning.
Seasonal adaptation adjustment
Keep the water temperature above 18℃ in winter and enhance ventilation and heat dissipation in summer. Use atomized humidification when the humidity is below 40%, avoiding direct spraying that affects water quality.
Through scientific selection of hydroponic plants and meticulous care, an aquarium ecosystem can achieve stable operation for several years. Regularly observe the growth rate of new leaves and the activity of fish, adjust the maintenance plan in a timely manner, and you can continue to enjoy this vibrant greenery in the water.
