These high-performance hang-on protein skimmers are specifically crafted to attach to the edge of your aquarium. Protein skimmers feature a straightforward design yet play a crucial role in maintaining the health of your aquatic environment. Each skimmer is equipped with a submersible needle pump, which employs needle-wheel technology to create ultra-fine bubbles. The surface tension of these bubbles effectively attracts organic waste and transports it up the column, where it is then "skimmed" into a collection cup for easy disposal. All of our protein skimmers include a needle wheel venturi pump as standard. This pump brings in air through the venturi air pipe, and as water flows through the needle wheel impeller, it breaks the incoming bubbles into a delicate mist. This results in enhanced skimmer performance. Please make sure that the outlet pipes of the skimmer are completely submerged for optimal operation. The water level should not fall below the maximum depth indicated below. This unit is suitable for sump use as a hang-on option.

Aqua Medic Calcium Reactor KR 1000 The Aqua Medic Calcium Reactor KR 1000 provides essential dissolved calcium for reef aquariums with a capacity of up to 250 gallons. This system is designed to be versatile and can function as a closed system. It can operate independently through a bypass system without being affected by the aquarium's water level, or alternatively, it can be installed within the crankcase. The KR 1000 features a port that allows for the integration of a PG threaded 13.5 electrode, which is used for measuring the pH level, along with a SP 3000 Dosing Pump to regulate the water flow. Key Features: Provides dissolved calcium for reef aquariums up to 250 liters A closed system designed for universal application Operable in a bypass mode, independent of aquarium water levels, or can be installed in the crankcase Includes a port for a PG 13.5 threaded electrode for pH measurement Equipped with an SP 3000 dosing pump to manage water flow

Aqua Medic Turboflotor 5000 Shorty  Building on the success of the Turboflotor 5000 series, we have crafted these robust protein skimmers designed for installation in cabinets. The Turboflotor 5000 Shorty 2 and the Turboflotor 5000 Shorty Compact bridge the gap between the Turboflotor 1000 multi, suitable for aquariums up to 500 liters (150 gallons), and the Turboflotor 5000 baby, ideal for aquariums ranging from 1000 to 2000 liters (250 to 500 gallons). The Shorties come in two sizes to accommodate most aquarium cabinets. Like their larger counterparts, they include a venturi pump and our innovative needle wheel technology. To supply water to the skimmer, an additional pump with a minimum capacity of 2000 l/h (500 gph) is required. The skimmer can also be directly linked to the aquarium's overflow. In such cases, it is advisable to install a bypass to regulate the water flow to the skimmer, particularly when using powerful return pumps.
