Super size with Sicce SDC 4000 Mk. II (Controller, 24V, Wifi)

ATB protein skimmers have achieved a perfect balance between the intake air ratio and the volume of water in order to achieve a constant, stable foam volume and turbulence elimination. The company ATB introduced the world's first skimmer with a revolutionary conical shape in 2001. Thanks to this, the contact time of the air and water is greatly increased, thus increasing the efficiency of the filtration process in the reaction chamber. By combining this effect with consistent micro bubble formation created by Airstar air pumps, you get a recipe for uncompromising performance that both amateur and professional aquarists require.
