Assuming you don't have algae problem:

1. Your tank is of over 120l of water. You'd better change your lighting system to T5HO 24Wx6.
2. Increase your CO2 input level to at least 4 bubbles per second.
3. Why your pH level varies so much, i.e. 5-7? What have you done? For ADA II soil, it should be around 5.5-6.0.
4. How much grass are there in your tank? Please post a photo for reference.
5. "水榕有黑點": Are you sure they are black spot? Or Green Spot Algae? Again, you'd better post a photo to confirm.
