I keep a double computer fan on all the time to keep temp down and keep heater going to keep temp up.Do you have a fan or chiller going all the time to

Having a fan on all the time probably explains why the heater is always on.

I'm running a controller for both fans and heater. One won't be on if the other is.

I have a reefkeeper which controls my heat with a 500w titanium heater. The heater is set in the skimmer compartment of my sump. I have a bypass style refugium. I took the temp sensor and set it in each compartment of the sump and also in the main tank. It showed a temperature difference of 0.1 degrees so I'm thinking nothing to worry about.

I have 2 heaters in my sump and I don't think they have ever turned on

Could you try putting them in your overflow maybe that will work better

A person told me to set the heater a couple degrees below my low temp.(76) This way the heater safeguards against the temp going so low it kills livestock.

try adding an additional heater!
I use to use 1 larger heater for my reef until a freind suggested for me to use 2 smaller, I scratched my head and asked why add 2 when I can use 1?
He replied if 1 small heater stuck on your reef wouldn't cook, the likely hood of 2 failing is very unlikely and if it did I would have to go buy a lottery ticket. btw total water about 180g and am using 2 200w

If your heater is working properly, you should be able to set it at your desired temp, and it should only come on if the temp drops below that. If you set it low, you will likely have temp swings at night. I've found it hard to get a good heater that is always consitsant. Mine is working fine now, but I don't trust it. I'm thinking the answer is a good quality controller and probe element.
