Answer: Yes, the heater comes with an easy and quick installation process. It can be placed vertically or horizontally using the attached adjustable hanging rack and suction cups. -
Question:
i got 800watts, if it have sensor outside the water , what happens if room gets really cold ? Is this heater going to fry my fish ?
Answer: I’m assuming the temp sensor is in the heater element inside my 75 gallon tank. The outside display shows water temperature and what heater is set at. Works great in my tank holds water temperature well. My tank is an add-on and room temp varies from the 50’s to the 80’s and I haven’t had any problems. -
Question:
Will this work for a 25 gal hydroponic reservoir? Heavy plastic tote, not a glass aquarium.

AQQA Aquarium Heaters GUS-AQ015-100W Editorial Review
The AQQA Fish Tank Heater 100W has garnered a generally positive reception among aquarists, praised primarily for its reliability and ease of use. Many customers have highlighted its effectiveness in maintaining stable water temperatures within a close range of the set value, demonstrating a reliable performance in various tank sizes—specifically in 25 to 35-gallon aquariums, but even in smaller tanks. The digital display feature has been frequently noted as a major advantage, providing users with a clear visual indication of both set and current temperatures without the need for additional devices. Setup appears to be straightforward, although some users have mentioned the absence of detailed instructions. Most found the pictorial guide sufficient. A recurring theme in reviews is the heater’s ability to maintain temperature, even in cooler environments, which is crucial for keeping fish healthy, particularly during winter months. Additionally, the heater's safety features, such as the automatic shut-off at 93°F, enhance user confidence. However, there are some drawbacks noted by users. The bulkiness and aesthetic appeal of the heater have not gone unnoticed, with some reviewers expressing dissatisfaction regarding its appearance and the fit of the digital thermometer with various aquarium setups. Noise from the heater's on/off mechanism has been noted as a minor inconvenience by some, although opinions on this aspect vary. Moreover, there have been isolated reports of malfunction after a few weeks of use, which raises concerns about long-term reliability for a small percentage of buyers. Overall, the AQQA Fish Tank Heater 100W stands out in terms of functionality and user satisfaction, making it a worthwhile choice for fish enthusiasts looking for an effective and user-friendly heating solution for their aquariums. **
