Why consider this model?

  • Consider this smallest Jäger size when a freshwater or marine tank is within its approximate 20–25 L / 5.2–6.6 US gal guidance, a 25 W heater is appropriate to the room and aquarium, and a short vertical glass rod fits below its marked waterline in strong flow.

Tradeoffs to weigh

  • Its documented upper rating is 6.6 US gal and its analog dial is not a water-temperature display. The glass body is not documented as shatterproof; verify the 120 V / 60 Hz label, water mark, immersion limit and exact package before use.
