Hey guys, so I’m in the planning stage of getting my automatic topoff and water change system going. I’m pretty positive I”m going to go with a Tunze Osmolator for ato and a stenner pump for awc. I’m currently running a 75 gallon sumpless system, but this should be an easy system to fit to a bigger sump containing system down the line. Anyway, my only real route to do this is to run the tubing out an exterior wall behind my tank, and along the outside of my house to the garage where my water storage is. This is a very straightforward path and project, but my only concern is during the winter how to prevent freezing issues. I’m in central Alabama so we don’t deal with anything too crazy. It’ll get to the teens, but that’s about it. I was thinking about running all the tubing through a PVC conduit and either using one of those pipe heaters from home depot or just wrapping it generously with some insulating tape. Do any of you guys have experience with this or suggestions?
