Aquarium water heater

Me using most the time for the first 10 days during primary fermenting. A swamp cooler. What now insted of ice jugs. I am using a aquaruim water heater. I can set the temp. So no need for ice jugs. Does this work

I use an aquarium water heater that has a maximum set temperature of 75°F in my swamp cooler in conjunction with a cooling fan when cooling is needed. I control the fan and heater with a STC-1000. This picture shows the swamp cooler without the aquarium heater. Only needed cooling for this fermentation.
