go...
As long at the temperature stays steady in this range, I don't see a problem. Sudden changes of several degrees would be a problem. But, I see nothing wrong.

1. 5yrs is awhile. A heater not a big investment.
2. 3-5w per gallon depending on your location/climate/room temps
3. In larger tanks consider two heaters for even heating and as a backup
4. Make sure thermoter is correct

No not normal or what I would want for my tank.
3 degrees up everyday and back down sounds like maybe the light is adding heat?
What is the heater set for? if it is set for 78 is it on when it is 79-80? If it is I would think to replace soon ,as you never know when it won't stop at 81?

I use titanium heaters with external thermostats on all of my tanks over 40g. A bit more pricey than standard heaters, but they're unbreakable, last quite some time, and never vary more than 1 degree F in temp. They also seem to heat the water to temp faster after water changes, if I get it a bit too cool. The thermostats also have surge protectors and safety shut-offs in case of any malfunctions.

^^ Good stuff there and I agree ^^
I use Aqueon PRO heaters which I order online to save a ton of money...
Very accurate and nearly indestructible. Black plastic encapsulating an aluminum sleeve that hides well in tank.
They rate size by the amount of gallons you need to raise "X" degrees above room temp.
For a 75 the guide says 200 watt will get your tank 10f over room temp of 68 -72..
If you want to be able to go 15f over 72 then 250 watt..
I have over 30 and still recommend them..Many like cobalt also...
