I set up a 20 long a week ago and I have an Aqueon preset 150w. I like the compact size compared to the adjustable models. Not sure of the thermostat tolerance on the presets, but mine keeps the tank at 76 and dips to 74 when it gets cooler at night. Ambient is around 70 year-round. The tank is covered. Heater is next to filter intake and heat is spread evenly based on my readings in different parts of the tank.
I would like to supplement the heat but not sure of what size to get because I thought I was already oversizing at 150w.
Should I consider moving to a 200w and keeping the 150w as a backup?
