Check the exact model and configuration against your choices, then compare the seller and offer details.
Explore this buying guide ↗Why consider this model?
- A possible fit below the conservative 100-gallon volume screen when an adjustable 400 W heater and the listed 18-inch height suit the installation. The current exact-page maximum is 130 gallons; the older official table lists 100, so this assessment chooses the lower supported common limit.
Tradeoffs to weigh
- The size and power demand more clearance and careful package verification than smaller HTG versions. The glass body is not documented as shatterproof, the published limit has a 100-versus-130-gallon conflict, and the reviewed manufacturer sources do not specify a voltage/nameplate range or minimum aquarium size.
