My uncle recently gave me a 10 gallon fish tank and he included an under gravel filter with it. Now, I have been researching undergravel filters on the Internet and I am not sure if I want to use it. I want to have a planted tank, but I have never done it before. Is this a good idea with an undergravel filter? What kind of substrate should I use? Should I use a substrate good for growing plants, like sand? Or gravel? Or should I use sand with gravel? If I only use gravel, how will the plants grow? My uncle recommended an Amazon sword plant, would that grow easily without sand-like substrate? And if I don't use an undergravel filter, what kind of substrate do I use? If I have an undergravel filter, should I use a regular filter as well? Sorry for all of the questions but I am new to this and need help! Thank you
