Anyone have a used temperature controller out there they want to sell? I have been reading stories about how the glass heater thermostats go bad occasionally and the water can heat up and kill everything in the tank. So I am interested in a temp controller. something that would be upgradeable such as adding a PH probe or light control would be nice but not a must.
Dual stage would be nice....Water to hot turn on fan, water to cold turn on heater
