heater in sump
Does a heater in sump work.My heater seems to be on all the time even though my tank is always 76-78.My thought isthe water in the sump passes through so quick does it really have time to heat the water or do all the pumps/power heads actually do the trick.Any comments would be appeciated.

IMO, it has a lot to do with the total system volume, the amount of turnover flow, and the wattage of the heater.

Would think if heater wattage was enough for volume, with any sort of flow, system would eventually reach a equilibrium.
btw, I have a 300w heater in sump, ~200g system volume, ~1000gph through sump and heater cycles.

I have a 300watt heater in the sump for 125gal and it is mostly off other than when the autofill dumps some water.

sump heater
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

heater
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.
