I set my a/c and heat for my animals comfort and survival. For three years, I lived in an apartment with only one window a/c unit. I used fans to circulate the cool air-I had no problems. Then, I moved into a house with central air. Everything was hunky dory, until the a/c went out on a holiday weekend. I had no a/c for 4 days. I turned off the lights, opened the windows, and used big gatorade bottles of ice in the sump to try to cool my main tank. The daytime temps were over 100F, and I couldn't keep my tank lower than 95F. I lost most of my animals. Perhaps, a chiller would have been the answer but here in Florida, we can also lose power for long periods too.
I don't think anyone on this forum is intentionally going to do something to jepordize the health of the animals in their tanks. We are all here to learn or to teach from what we have experienced. As teachers, we should be patient and remember when we made mistakes. We should also remember that we don't know everything and when we quit learning, we may as well just hang it all up.
