A 2-3 degree temp swing (78F-81F) is okay in our tank.

It's your pumps creating heat, is there a way to keep the fan on all the time? It will help to gas off CO2 as well.

What size tank is it and what type of powerheads? Many pumps and powerheads generate a fair bit of heat.
Try unlpugging one or two powerheads for a day and check your temp. That should give you an idea of how much they are contributing.

I have four T5s and two 6 foot VHOs and 3 250 watt halides and they heat my water by about 1 degree.
My Pumps (Sequence Hammerhead, pcx40, pcx50, pcx30, and Blueline 100) heat my water by about 14 degrees! Keep in mind all the above pumps are external, so they heat the water less. Submersible pumps heat the water by quite a bit.

It is a 72 gal and the powerheads are all hagen 3x201 and 1x402 plus the Mag350 for the skimmer.
I have noticed that the temp has started to decrease as the weather is getting a bit colder... My heater has been actually unplugged for 4 days now!!! I am considering of running without a heater even!!!

I wouldnt remove your heater. If the thermostat is working it properly the heater won't contribute to a heat problem but it will protect against a temperature drop should the ambient temperature get cold.

I havent used a heater since june. I am kinda concerned about the tank temp though in the mornings it will be about 73 and by night time it will be at about 79-80.
