Fluval Submersible LCD Aquarium Heater

Size

Advanced Electronic Aquarium Heater

The LCD temperature display provides peace of mind as the actual aquarium water temperature is continuously displayed in either Celsius or Fahrenheit. During normal operation the temperature read out will change color if the aquarium water varies +/-1°C or +/-2°F or more from the preset temperature.

  • LCD displays actual water temperature 
  • High/Low temperature alert 
    • Should any external heat sources or other equipment, such as chillers, cause the aquarium water temperature to rise or fall beyond 3°C or 5.5°F, the colored screen will flash, indicating a potential risk.
  • Precise and easy temperature adjustment
    • With the easy to use adjustment lever the temperature can be precisely set in 0.5°  increments
  • Advanced fish protection
    • The integrated fish guard offers advanced protection. Fish and invertebrates cannot come in direct contact with the heater core. The heater is protected against shocks from large fish species.

Didn't live up to expectations

I bought this heater for my 40 g breeder tank to replace an old Eheim-Jager. I have my heaters set at 78 degrees. In the winter, we set our thermostat to 65 deg at night, and 72 during the day. I bought the 200w Fluval E heater thinking it would keep the water temp near 78, even during the night when the air temp dips to 65. Unfortunately, the heater was not maintaining the set temp, dipping down to 73 degrees at night. I like the features of the heater, like the colored lcd panel that measures the temp and the ease of changing the setpoint. The performance was not there however, and I ended up replacing it with a Hydor inline heater. I have had very good results with those in the past. I wouldn't recommend the Fluval heater for those expecting to keep the aquarium water more than 10 degrees higher than the ambient temperature.

Great heater

Great heater. Definitely need good flow or you'll get the low flow warning. Under gravel filters alone were not enough. Positioned a small circulation pump directed at heater and resolved the warning by the next morning. Maintaining temperature within a half degree.

Great experience. Paid more to get from the co-op

I have never purchased anything from the co-op before, but I needed a pair of heaters for a new tank. I had remembered a video Cory put out about this heater and gave it another watch. To be honest, I paid a little more to buy it here, but I would have never known about this heater if it wasn't for Cory. I think he deserves the business for all he does for the hobby, and if I have to pay a little more for great customer service, I'm more than willing to do so. Thanks for all you do and for a great purchasing experience.
