| I picked me up a digital thermometer today at the pet store in the mall. Its a Coralite one I believe. Its black and battery operated. Can the probe be hidden in the back in one of the chambers you think or does it have to be out in visible sight? I think I may try just a Y-Connector at first and see how that does. I was thinking about running carbon or some purifier in one of the filtration chambers. |
