AquaTop Quartz Platinum QPH-300 300 W Aquarium Heater
Model: QPH-300 (300 W)
This exact QPH-300 reference rests on the AquaTop 2021 QPH family manual and 2022 Platinum cutsheet; the model review retains an exact-item body label and carton image observation. The reviewed material does not establish a present US offer, current lifecycle or the package a seller will ship.
This model lookup is separate from the questionnaire shortlist. It does not certify that this model meets your selected requirements.
Exact-model photograph is not verified. This reference lookup is text-only. The exact QPH-300 image and carton observation remain in the source-side review; no sibling or family image is substituted here.
AquaTop lists QPH-300 at 300 W, 15 inches and 55–100 US gallons. The exact QPH-300 carton image in the detailed review says 80 gallons maximum; the assessment uses 80 only as a conservative comparison ceiling and does not infer that the older official band is corrected.

Documented model details
- AquaTop’s family sources list the 300 W QPH-300 at 15 inches and in a 55–100 US gallon band; the exact-item carton shown in the review states 80 gallons maximum.
- The QPH instructions allow fully submerged in-tank mounting vertically or horizontally, in fresh or salt water, with the water above the marked minimum line.
- The family uses an adjustable analog thermostat with a stated 68–93°F range and heating indicator; its quartz-glass body is described as shatter-resistant.
Limits to weigh
- The official 100-gallon upper band conflicts with the 80-gallon carton maximum. The detailed assessment uses 80 as a cautious comparison ceiling without resolving which current package or written guidance applies.
- The stated 55-gallon lower edge cannot be enforced by the finder’s maximum-only rule; QPH-300 is a reference and not an active finder match.
- No control-accuracy tolerance, shatterproof claim, impact rating or confirmed included guard is documented. Current US availability and seller package are not established.
Check before ordering
- Verify the actual product and carton are QPH-300 / 300 W and UPC 810281019062; ask for current written capacity guidance before treating 100 gallons as supported.
- Check the supplied unit label, instructions, electrical input and package contents; allow clearance for the 15-inch body and required waterline.
- Measure actual water temperature independently and assess the room-to-target difference rather than treating wattage or a gallon label as a heating guarantee.
