Abstract: An aquarium skimmer device can include a filter body that attaches to a water pump, filter, or power head, wherein the filter body is configured to hold a filter medium for filtering water that passes through the filter body. The skimmer device can also include a funnel holder that attaches to a top of the filter body, and a funnel assembly comprising a funnel. The funnel assembly can be received by the funnel holder and configured to float up and down with respect to the funnel holder with changes in water level, and a wide opening of the funnel is positioned one inch or less below a surface of the water.
