water is looking greenish

Or you can try a chemical product called Green-X or Algae Destroyer. Those will kill off any algae and/or plants in the tank. I use it in my boyfriends parents koi tank because they get direct sunlight on the tank...works wonders, especially for green water.

i was also going to mention... why dont you get some more gravel? it will help with your water quality stability if you give nitrifying bacteria more room to grow
