Had a pretty hot day here in Jersey and I didnt have my ACs running yet because we usually expieremce all 4 seasons on one week but my tank temp jumped to 84 degrees. Everything seems to be fine in the tank. But could I put some ice in a plastic bag to help cool down the water until my house gets cooled off.
 
Ice is very inefficient, but a fan blowing across the water makes a yuge difference.

For the rest of the US, that is “huge” in NJ.

Could I put the fans on my sump? I disconnected the heater and got the temp down to 80.
 
Any fan will do, but there are specialty fans you can buy. I use an air mover because it helps to circulate the air in my basement to my dehumidifier, but the goal is simply to move humid air away from the tank and allow evaporation to cool it.

Your heaters being plugged in shouldn't make any difference. If they were still running, the temp might be set too high. I've got one heater that 72 indicated is actually 78.
 
What @Breadman03 said. If unplugging your heater resulted in a drop in temperature, there is something wrong with your heater or your heater's setpoint.
 
Dont skimp on the quality of the fan unless you will only use it once in a while. Cheap fans can have the motor heat up and seize. This can cause a fire. Has been known to burn down many a chicken coop.

The heater is fine I keep it at 79 because during the cooler months it would keep my temp at a steady 77 but I just disconnected it to be on the safe side.

I am a beginner at the aquarium tank world. But I noticed that I had to set my heater at 72 and the temp stays at 76-78. The heater is attached to one end of the tank near good water flow and thermometer is on the other end of the tank. The dial is not accurate on mine. My temp shot up to 87 before I realized the dial was inaccurate. I turned my AC up in the house and lowered the heater dial until I reached the desired temperature. So glad I noticed this before adding livestock.
 
What kind of a cooling fan do you have? I’m not really sure what to get.
I have a little cheap white fan with the big spring clip on it.... have plugged into my Reef keeper lite and programmed for on and off temperature....
 
Open your windows
This works in CA on the coast in the summer when its 60F outside. May not work here in Texas when its 100F and 99.9% humidity.
 
IMO easiest way to temporarily reduce temp in a fish tank is to take a couple of 2 liter bottles, fill with water, and throw them in your freezer. If/when you need them just throw in your sump and it will do a great job as a temporary fix. As the water melts it will stay in bottle and not disturb your salinity.

One thing to remember with a fan is that the water will evaporate much faster, so the fresh water top-off will come up a lot quicker. Best to keep some ready as you'll use more.
