Here is a picture of my filter nets.



They look quite a bit different than yesterday. Now when I pick up the net as you can see some of the stuff stays attached to it. It has also turned bright green. I put a couple tablespoons of Miracle Gro in last night. I bought some ammonium sulfate and only put in one tablespoon today because it has a lot more ammonia than miracle gro did but I'm going to give it a try. I noticed the pond was turning kind of a brownish green yesterday before I fertilized it. I hadn't added any since I added the fish. My ammonia was still well below 1 ppm before I added the ammonium sulfate. I will test tomorrow and see if it climbs.
