Tunze Aquarium Pumps, Skimmers & ATO

Dive Deeper: Tunze Equipment by Model

Tunze catalogues by part number, which is precise but unhelpful if you do not already know the range. Here is the map.

Turbelle NanoStream and EcoStream Pumps

NanoStream 6040, 6055 Eco, 6075, 6095 — compact circulation pumps for nano through mid-size reefs, with a wide flow pattern designed to move water across rockwork rather than through it. The Eco variants draw less power for the same output.

EcoStream 6105 and Turbelle EcoStream 6255 Eco — the larger circulation pumps, controllable and suited to reefs from roughly 100 gallons up.

Turbelle High Jet — high-pressure output where you need a directed stream rather than broad flow.

ORCA MK2 oscillating mounts (solo, 6105, 6075) — motorised mounts that sweep a Turbelle pump back and forth, producing genuinely variable flow patterns from a single pump.

Comline DOC Protein Skimmers

9001, 9001 DC, 9004, 9004 DC, 9012 DC — in-tank and hang-on skimmers designed for nano and mid-size systems with no sump. The DC models add controllable, variable-speed pumps. These are the reference skimmers for all-in-one and rimless nano builds where an in-sump unit is not an option.

Osmolator ATO Systems

Osmolator 3 and Osmolator 3 Nano — auto top-off with optical sensing, a mechanical backup float and an audible alarm. The redundancy is why they have the reputation they do: a single-sensor ATO failure floods a tank, and the Osmolator is built assuming the primary sensor will eventually fail. Replacement metering pumps are stocked separately.

Macroalgae Reactors and Refugium Lighting

MAR-3181 and MAR-3182 macroalgae reactors for contained chaeto growth and nutrient export, and the Eco Chic Waterproof Refugium LED 8831.
