To ensure the health and longevity of your built-in indoor aquatic plant garden, it's crucial to maintain proper water filtration and circulation. Install a high-quality filtration system that can effectively remove impurities and keep the water clean and clear. This will help prevent the growth of algae and maintain a balanced ecosystem within the garden. Additionally, consider incorporating a small water pump or fountain to promote water circulation. This not only adds a visually appealing element but also helps oxygenate the water, benefiting both the aquatic plants and the koi fish. Regular maintenance and monitoring of water quality are essential to keep your garden thriving.
