After discovering what was causing the high temperature in my aquarium the next step is get to a desired temperature and maintain that temperature as best as possible. Currently the Apex Aqua Controller configuration for the outlets that my Eheim 300 watt heaters are plug into are set to monitor the temperature probe and either turn on at 77.00 degree Fahrenheit & turn off at 78.00 degrees Fahrenheit. After letting this run for about 1 day I started to see a nice trend created by the Apex Aqua Controller. It appears that I have a variance of 1.1 to 1.2 degrees. So I made additional adjustment to the outlet setting to decrease the variance to at minimum 0.5 degrees and also hit a average temperature of 77 degrees this morning. So I will let this run for about 1 day and see what the results are.
