I was wondering what everyone is doing? I have a Finnex HC-810M controller for my temperature control. But I also have the apex. Should I plug my heater element to the Apex? I can’t seem to set my high on the Finnex to anything lower than 80. My tank maintains between 78 and 79F. Now that I have a Blue spot jaw fish I want to run it between 77-78 but I can seem to figure it out using the finnex. What do you all say?
