    Without surface skimming, a tropical aquarium (especially if CO2 injected) quickly develops a surface layer of bacteria. This layer prevents proper oxygenation of the water, which can be harmful if the tank is not planted heavily enough.

    Here are some closeups of exactly how this layer looks like. It is clear to me that there are multiple different species go bacteria just going on morphological differences. And naturally, as many organisms feed on microbes, this is the ideal place for a nice buffet. Just sad the bacteria seems to be winning...
