My filters seem to be holding their own. Do you guys think three filters will be plenty? I would still like to add two more for good measure. The water looks pretty much the same color as yesterday. The Ammonia is 1 ppm. I also think I did the test wrong the first time I did it and got a false low reading. I wish I had done one yesterday. I think not feeding the fish is the best thing I can do till it goes down. I put some catfood in the blender and finely powdered it. Now I can give them a small pinch and it entertains them (and me) for a good 5 or 10 minutes. The same amount even crushed up is gone in five seconds.
