ATB skimmers achieved a perfect balance between the ratio of intake air and the volume of water in order to achieve a constant, stable foam volume and eliminate turbulence. In 2001 ATB introduced the world's first skimmer with a revolutionary conical shape. Thanks to this design solution, the contact time of air and water is significantly extended and thus the efficiency of the filtration process in the reaction chamber is increased. By combining this effect with the consistent microbubble formation created by ATB air pumps, you get the recipe for uncompromising performance required by both amateur and professional aquarists. Extern skimmers are designed, to be placed outside the filter. They are watertight and their pump is located next to the skimmer. Thanks to this, the volume of the skimmer is maximized, the contact time is extended and the filtration is maximally efficient. This design also makes the skimmer and pump easier to maintain. External skimmers must be fitted with a pump which supplies water to them. They are equipped with overflow protection as standard.
