3 year old fish tank , cloudy water
3-year-old 115-gallon fish tank water became cloudy. I'm pretty sure it was the water perimeters because of the nitrate and ammonia Spike. I just did a 50 percent water change, in which the water is still cloudy. Also, what's strange is a lot of the fish poop is floating on the top of the tank.
How do I stop the cloudy water, and why poop is floating on top of the tank.
