Fluval Edge Compact Heater
Installation
Generally, the heater should be placed at the rear of the aquarium, preferably close to a source of water movement to ensure even and thorough distribution of warmed water.
Position the heater in the aquarium and press suction cups firmly against glass or plastic to adhere to the aquarium wall.
Make sure heater remains submersed at all times.
Allow heater to acclimatize to the aquarium water temperature for 10 minutes before plugging it into the electrical outlet.
Maintenance
Caution: Unplug all appliances in the aquarium before placing hands in water. Unplug the heater and allow it to cool for at least 30 minutes before taking it out of the water.
Clean the heater regularly to remove deposits that could impair the heater performance.
Deposits on the heater can be removed by soaking it in vinegar and then rinsing it with fresh water before repositioning it in the aquarium. Do not use chemical cleaners.
Fluvel heaters
2 out of the 3 I’ve used failed to keep to the so called preset temp of 26 degrees. Yep got up on 2 occassions, fluvel edge became a graveyard for all my now dead plants and part boiled fish. 32 degrees at least.
Put it down to a dodgy heater. Put a standard one in there and gradually restocked. Bought another slimline fluvel heater and 3 days later same thing happened again. Result was boiled fish.
Lovely tanks when set up and all lit up. A real pain to clean and your fluvel nets are worse than useless.
had 3 had to replace them they wouldnt switch off
