I got a top fathom 100a used and have it running in my sump for a good 2 weeks now and I'm having a hard time tuning it to get a dark sludge that I see in so many peoples skimmers. Its in 8 inches of water and I have the bubble level set about 2 inches below the top of the neck. The bubbles will slowly over flow but I get more water then skimmate. After 24 hours its full of water that's got a slight tan tint to it. If someone can tell me how to tune this that will be a great help. I'm sure its somthing simple. Thanks
