new sump= Major problems

[Ghost]

I am going to double check mine this evening with another one. The one I have in there now is a digital type with the cord submersed in the tank. Being that I bought it brand new and saw it climb (when I first added colder water) and plateau, I would think it is. But I'm going to double check everything. If I spent a ton of time trying to figure this out only to learn it was something that simple; I'd go postal.
