I am rocking a 6.6 fluval chi, aqueon heater (50 watt) and a finnex fugeray with a marina temperature thermometer. It's reading 82 degrees and is fully planted with 2 otos and 20+ ghost shrimp. How do I lower the temperature or is my thermometer broken? The heater turns on sometimes...
just bought this thermometer:
Amazon.com : Marina Floating Thermometer with Suction Cup : Aquarium Thermometers : Pet Supplies
It's stuck on 82 degrees and hasn't shifted at ALL. Anyway to fix?
