Finnex HMA-150s 150 W Titanium Aquarium Heater

Exact-model photograph is not verified. This reference route is text-only. The normal review's official HMA-series image is captioned as family appearance only; it does not identify the exact 150 W assembly or package. No HMA-150s-specific product photo is verified.

Finnex lists the HMA-150s at 150 W for 30–60 US gallons, a range with a meaningful 30-gallon floor that this site's finder cannot enforce. The HMA page also states a 68–92°F control range and a ±2°F family claim, but does not establish this exact retail package, full electrical rating, or installation instructions.

Documented model details

• Finnex's family table names HMA-150s at 150 W, lists 1.35 A at a 115 V reference, gives a 68–92°F control range, and specifies a 30–60 US-gallon band. The band is a manufacturer statement, not a heating guarantee for every room or aquarium.
• The family overview describes a titanium tube, an analog controller, an LED heating indicator and a heater guard with suction cups; it also claims freshwater and saltwater use and temperature maintenance within ±2°F of the setting. The page also uses the phrase ‘electronic control,’ so this is not a precise control-interface specification.
• Finnex's sizing footnote limits the table rating to a standard enclosed aquarium and describes maximum heating capacity as ±8°F above ambient room temperature. That manufacturer qualification is relevant to the tank's room-temperature difference; it is not independent performance evidence.

Limits to weigh

• The 30-gallon minimum is essential. The current numeric finder rule can check only a maximum; this 30–60-gallon product remains outside active matches rather than being treated as suitable for every tank up to 60 gallons.
• The reviewed manufacturer materials do not establish the retail SKU/UPC, exact seller package, complete allowed supply voltage/frequency, body dimensions, a wattage-specific product photograph, or HMA installation/submersion instructions. The instructions index does not list an HMA manual; instructions from other Finnex families are not transferred.
• The ±2°F figure is a manufacturer family claim with no reviewed test method, and no numeric selector increment is documented. The analog/electronic wording is not resolved into a second control mode.

Check before ordering

• Check the offered model text and carton against Finnex HMA-150s / 150 W, not the HMA-100s or HMA-200s. Finnex's reviewed family page does not establish a retail SKU or UPC.
• Before purchase or connection, verify the actual unit's complete electrical nameplate and obtain current HMA-specific directions; 1.35 A at 115 V is only the source's reference point, not a complete voltage/frequency rating.
• Treat 30–60 gallons as Finnex's stated band for a standard enclosed aquarium, consider the room-to-water temperature difference, and verify the required placement, immersion and clearances from exact-model instructions rather than inferring them from a family image.
• Check that the actual package includes the components you need, including any guard/suction-cup parts; the family description does not prove the contents of a particular seller's offer.
