I had a running 10 gallon that I just used for extra plants and surprise lampeye fry. I decided to redo it and add flourite, hoping for better plant grow. If all goes as planned, it'll be my least killifish, Heterandria Formosa, winter tank. I gently washed the flourite in a wide container and basically just let the red water flow out of the container, it took about 30 minutes. After letting the fourite dry, I emptied the tank, and added the dry flourite. Slowly added water, the water didn't turn red, big surprise! There was just a thin layer of something on top of the water which I removed with a paper towel. Even with planting, the tank never got really cloudy, the last picture was taken about 3 hours after I was done. I will add more plants in the background and wood. Before the fish move in, I'll add leaves in the front of the tank. Any suggestions?
