Summer Time and Aquarium Temperature

[highest_tides]

I know a lot of people use chillers but, I was wondering if anyone just regulates their house through AC. I've decided to just keep my house around 75F but it's the idea that you are on top of it at all times and I guess I'm so new I don't understand/want a chiller for the water with a heater? I'm in CO where the temp can flucuate from 35F to 70F in a 24 hour period in the spring. Sometimes our windows are open but then it will get really hot out and we won't be around to turn the AC on..thoughts?

I keep my house at 68 and don’t need chillers in CA.
