No that hasn't been pointed out but I did consider it. I am thinking of going the under tank heater for this reason....is there any reason I couldn't use one w/ an acrylic tank? I am also getting a humidity meter first chance. You guys are all very helpful. As the profile says it is Kim and Donna, if the forum is kid friendly (seems to be so) I would like to let Donna on here to pick your brains, as she will be the main care giver soon.
