100 W heater

[ShadyFish04]

I have my 20 gallon tank and it has a 100W heater. I was researching ich, just in case my fish get it one day, and learned that the parasite cannot reproduce in 84+ degreed F. My question is, how do i aide the temperate of my water? My heater keeps the water at a 76F, is there a way of increasing that or decreasing if necessary? The brand is by Aqueon

Is it a preset? If it is then buy a new one, you can't change preset heater temps as they're set to 78°. So get a heater and any will do as long as it doesn't say preset and it's 100 watts or higher
