Snoop's Take

The AQQA Aquarium Heater 500W is designed to provide a reliable heating solution for large fish tanks ranging from 66 to 135 gallons. Made of durable quartz glass and equipped with an external temperature controller, this heater maintains a consistent and safe temperature for both freshwater and saltwater aquariums. Consumer feedback highlights the effectiveness of the external temperature controller, with users noting that it "shows the current temp & your set temp" and keeps a stable temperature once set. Many have reported that the heater performs well, with comments like "it’s been awesome tbh" and that it can even be completely submerged without issues. However, some users have raised concerns about reliability, mentioning potential overheating and failures post-warranty. Overall, while the AQQA Aquarium Heater 500W has received positive feedback for its performance and ease of use, potential buyers should be aware of the reliability issues noted by some users. Therefore, it may be recommended for those who prioritize performance but should be used with caution regarding its longevity and safety.
