That is a great article. However, I am not solely basing my dissatisfaction on the color or consistency of my skimmate... it's the rising levels of nitrates that concern me. It seems that no matter how I adjust the CS2, I cannot get it to pull enough out of the water to maintain the levels I was used to with my old SWC. That was why I stated that I must be doing something wrong... because, a skimmer that retails for this much and is rated for tanks well over my size, must be capable of maintaining 0ppm Nitrates in a tank as sparsely populated as mine.
