- The 300 W HeatUp 300 is longer than the 150/200 W bodies: 370 mm / about 14.6 inches. The exact specification row lists 300 L; US page copy says 80 US gal. The litre conversion is about 79.3 US gal, which is the conservative matching ceiling. OASE names BioMaster 600 as an external-filter integration option; the alternate FiltoSmart 300 arrangement requires a separate ThermoFit 48567.
Tradeoffs to weigh
- The US technical table says 115 V / 50–60 Hz, while narrative voltage copy says 230 V; inspect the precise product’s label. The 80 gallon headline exceeds the 300 L conversion by a small amount, so the active ceiling is 79.3 gal. The external route assessed here requires BioMaster 600. FiltoSmart 300 is an alternate route only with the non-included ThermoFit 48567.
