Newbie question: Water change for temperature control?
I've just started a 20 gallon planted tank (2nd week) and have managed to maintain a temperature between 72-74 degrees. With a rare heat wave, I came home to a temperature of 80. I don't have any live critters yet (other than six snails that magically appeared) but decided to experiment. I removed a gallon of water and added a gallon of cold water, treated of course. This brought the temperature down to 73.5. From what I can tell, it didn't affect the snails.
If I had fish or shrimp, would this have caused a problem? What is a greater risk, a steadily rising temperature or a reduction in temperature?
If what I did was a bad idea, how can I reduce the water temperature?
Of course, it was a temporary solution as after two hours it's now back up to 76F.
