For all you home pool room guys. If I keep the temp in my room at 70 degrees when occupied what is the allowable temp that I should keep it when not in use. Overnight in summertime temps. Currently I am keeping it at 77 degrees overnight to conserve energy. I have only had the room for 3 weeks. Have not received first power bill yet. Would it hurt the table (affect the play)to let it get to 80 when not in use.
