Aqueon Pro Adjustable Heater 200 W

The exact AP200W-H manual row recommends 50–75 US gallons, while Aqueon’s 2025 catalog gives the matching Pro 200 W item a 75-gallon ceiling. The 50-gallon manual floor cannot be enforced by the current finder, so this is a model reference rather than a fit recommendation.

Documented model details

• Aqueon’s exact AP200W-H manual row recommends 50–75 US gallons, lists 13.0 inches overall length, and names 120 V / 60 Hz. The 2025 catalog identifies item 100532086 / UPC 015905000604, states up to 75 gallons, and separately gives 1.5 × 1.75 × 12.75-inch item and 3.5 × 1.5 × 12.875-inch package dimensions.
• Aqueon’s sizing table is based on a 68–72°F room and changes wattage with the desired rise. At 55 gallons it lists 150 W for 5°F or 10°F and 200 W for 15°F; at 75 gallons it lists 200 W for 5°F or 10°F and 300 W for 15°F.
• Aqueon describes adjustable 68–88°F control and manufacturer-stated ±1°F precision. Its red light indicates active heating rather than actual aquarium-water temperature, so the manual calls for checking a reliable thermometer and waiting 24 hours before reassessing an adjustment.
• The maker describes a thermal-plastic body over a metal core, freshwater/marine use, full submersion, vertical or horizontal mounting, tilt and overheat shutoffs, a marked waterline, and suction cups. The manual also calls for circulation, a drip loop, 30 minutes underwater before power, and no dry operation.
• The exact UPC-specific package image visibly identifies Pro 200 / 200 Watt and the carton’s up-to-75-gallon claim. It is a package-identity view, not heater clearance or performance evidence.

Limits to weigh

• The exact manual recommends no less than 50 gallons. Because the current matcher tests an upper volume limit without an enforceable per-model lower bound, Pro 200 is excluded from finder matches and ordinary questionnaire purchase recommendations; its separate reference page is not a compatibility verdict.
• The chart assumes 68–72°F room temperature and specifies different wattages by temperature rise. Those are manufacturer planning values, not independent heating-rate tests or guarantees for a particular room and tank.
• The 13.0-inch manual overall length, catalog item dimensions, and package dimensions are not interchangeable or installed-clearance measurements.
• The ±1°F figure is a manufacturer specification, not tested calibration. The indicator is not a digital water-temperature display; use a separate thermometer.
• The verified product identity does not establish current seller stock, condition, or package shipment. Confirm the wattage, item number, UPC, and exact offer before ordering.

Check before ordering

• Verify Aqueon Pro 200 W / AP200W-H / item 100532086 / UPC 015905000604; do not substitute a 150 W or 300 W neighbor or infer compatibility from the 75-gallon catalog ceiling alone.
• Compare the manual’s 50–75-gallon range with the actual working volume. Use the sizing chart with its 68–72°F room assumption and target-rise columns, not as a guarantee.
• Check installed clearance, marked waterline, circulation, drip loop, and cord routing. Keep vertical placement above the marked minimum or horizontal placement fully submerged; wait at least 30 minutes submerged before power and never run dry.
• Use a reliable separate thermometer, allow 24 hours before reassessing settings, and treat the red light as a heating indicator only.
• Inspect the exact offered carton and item/UPC. The listed lengths and the package photo do not establish tank-specific clearance or what a seller will ship.
