Explore this buying guide ↗Why consider this model?
- Consider the FiltoSmart Thermo 300 only if an external canister and an included 300 W heater answer a real preference for a combined filter/heater package, the exact heater voltage label is verified, and a compliant next-to or under placement is available. The maker's 80-gallon and 300-litre labels are upper limits, not a complete aquarium range or stocking rating.
Tradeoffs to weigh
- Thermo 300 SKU 55165 is a different package from filter-only standard SKU 55162: it adds HeatUp 300 SKU 33805 and ThermoFit SKU 48567. The HeatUp page conflicts on voltage, the filter page's 5.0-ft and 1.30-m maximum-head figures are not equivalent, and neither the upper-only tank labels nor 6.4-L total filter volume establish a lower tank limit or basket capacity. Maximum flow is not installed circulation, and no high-waste rating is documented.
