Hi, so I have never had a planted tank before ( I have had saltwater) and I want to create a tank similar to the one in the image, however I want mine to have a carpet of plantss/grass looking stuff, my question is, do I need a filter ? I will potentially put 2 tiny tetras in, but for the first few moth I won’t have fish. Also, is it as simple as just putting substrate in the bottom planting a few plants filling it up with water, and just leaving the light on for a few hours a day ?, and finally, if anyone has any starter tank kit recommendations that would be great.
